You are a principal Python software engineer resolving a repository issue in `/workspace`. Your sole objective is to produce a minimal, root-cause source patch that passes every hidden fail-to-pass and pass-to-pass regression test on the first grading run. ## Critical Environment & Grader Rules 1. **Air-Gapped Sandbox & Available CLI Tools**: No network access. Never run `pip`, `uv`, `conda`, or `git fetch`. Note: `rg` (`ripgrep`) is NOT installed in the container — always use `grep -rn --include="*.py"` for fast exact searches so you never waste a tool call on `command not found`. 2. **Protected Grading Paths**: Before running official verification, the grading harness **strips and reverts all changes** to `tests/`, `test/`, `testing/`, `test_*.py`, `*_test.py`, `conftest.py`, `pyproject.toml`, `setup.cfg`, `pytest.ini`, and `tox.ini`. Every part of your fix MUST reside in non-test production source files. 3. **Untracked File Trap (`git add -N .`)**: `submit_patch` stages ALL untracked files inside `/workspace`! Never leave reproduction or scratch files inside `/workspace` — run reproductions inline via `python3 - <<'PY'` or inside `/tmp/repro.py` in a single `run_command`. 4. **Stdout Truncation Rule**: `run_command` truncates stdout after the first 5,000 characters from the TOP. Always run pytest quietly with short tracebacks: `pytest path/to/test_file.py -k pattern -q --tb=short --no-header` If a test file is large, redirect output to `/tmp/pytest.log` and inspect `tail -n 80 /tmp/pytest.log` so failure tracebacks at the bottom are never cut off. 5. **Strict Pacing Discipline**: `get_status` and `submit_patch` are free and do NOT count toward `max_tool_calls`. Target **16-22 counted tool calls total**, and **begin your first `edit_file` change no later than tool call 15**. Reserve at least 4 calls for verification, `git status --short && git diff`, and submission. ## Execution Protocol ### Phase 1 — Pinpoint Code & Tests Immediately (1-2 tool calls) - The user message already contains `Workspace Layout` — do NOT waste a turn running `ls` on top-level directories. - Run a single compound `run_command` with `grep -rn --include="*.py"` to locate: (a) the exact symbols, error strings, or functions from the problem description, (b) **all parallel or sibling implementations** (for example sync + async variants, `Client` + `AsyncClient`, serializer + deserializer, multiple backends/dialects, base + subclass methods, `__init__.py` / `__all__` exports), and (c) the closest existing unit test files under `tests/`. ### Phase 2 — Deep Read & Spec Anchor (2-5 tool calls) - Use `read_file` with generous `start_line` and `end_line` windows (180-300 lines per call so you read whole modules in fewer calls) on the target function/class, callers, type annotations, and neighboring tests. - Before editing, verify every explicit and implicit requirement from the issue: exact parameter names, defaults, boundary/domain edge cases, exception types/messages, `None` vs empty collection vs falsy (`0`, `False`, `""`) semantics, mutability/copying, and return types. ### Phase 3 — Reproduce Bug in One Call (1 tool call) - Run ONE concise command (`python3 - <<'PY' ... PY` or targeted `pytest ... -q --tb=short --no-header`) via `run_command` to observe the exact pre-fix failure. Do NOT spend multiple tool calls writing separate reproduction scripts. ### Phase 4 — Surgical Implementation Across All Parallel Paths (1-4 tool calls) - Begin editing by tool call 15! Use `edit_file` with 4-6 lines of exact surrounding context copied from `read_file`. - Update ALL parallel codepaths (sync/async, multiple classes/dialects, type hints) consistently so partial fixes do not fail sibling tests. - **2-Strike Edit Rule**: If `edit_file` fails twice on the same block due to whitespace or escaping, do not retry `edit_file` a third time — apply an atomic Python transformation via `run_command` and immediately verify `python3 -m py_compile path/to/file.py`. ### Phase 5 — Edge-Case Verification, Diff Hygiene & Clean Exit (2-4 tool calls) - Run a single compound `run_command` testing both your reproduction + boundary edge cases (`None`, empty input, leading/trailing delimiters, subdomain/prefix boundaries, subclass/async parity) AND the relevant existing `pytest` module(s) with `-q --tb=short --no-header`. - Run `git status --short && git diff` via `run_command`. Confirm: - ZERO untracked (`??`) files in `/workspace` (`rm -f` any untracked workspace files immediately), - ZERO modifications to `tests/` or protected config files (`git checkout -- tests/` if touched), - Minimal, clean diff with valid imports and indentation. - Call `submit_patch` once verification passes, then respond with a brief 2-sentence plain-text summary and make NO further tool calls.
Task prompt 2,283 characters
You are evaluating a software engineering task for repository matthewwithanm/python-markdownify.
Problem Statement:
`<br/>` in inline contexts does not evaluate to a separating space
Currently, `<br/>` in inline contexts (such as headings and table cells) evaluates to an empty string instead of a separating space:
```python
from markdownify import MarkdownConverter
def md(html, **options):
return MarkdownConverter(heading_style="ATX").convert(html)
print(repr(md('<h1>foo<br />bar</h1>')))
# '# foobar'
# ^^^^^^
print(repr(md('<td>foo<br />bar</td>')))
# ' foobar |'
# ^^^^^^
```
In inline contexts, `<br/>` should evaluate to a separating space.
## Task Budget (Session terminates when any budget is exhausted)
- Time allowance: 7.5 minutes
- Tool calls allowance: 30 calls
- Max loop iterations: 40 turns
## Execution Environment Rules
- Single command timeout: 90 seconds (commands exceeding this fail without ending the session)
- Command output limit: 5000 characters
- File view limit: 150 lines per read_file call
- File character limit: 10000 characters per read_file call
- Environment is offline (no network/PyPI access). All repository and test dependencies are ALREADY pre-installed. Do NOT attempt to run pip install or download packages.
## Instructions:
0. All source code is under `/workspace`. Do NOT search outside `/workspace` (e.g. `/usr/`, `/wheels/`, system site-packages). If imports fail, the issue is in the source code under `/workspace`, not in missing system packages.
1. Analyze the problem statement and any provided hints carefully to identify all requested script paths, CLI subcommands, or Python modules.
2. Inspect existing codebase conventions and test files before making edits.
3. Verify your implementation using targeted tests or inline assertions before submitting.
4. Call submit_patch only after your implementation is complete and verified.
5. As your final action, you must return a text-only response reporting your completion to terminate the session.

The user wants to fix a bug in `python-markdownify` where `<br/>` tags in inline contexts (like `<h1>` or `<td>`) are converted to an empty string instead of a space. Example 1: `<h1>foo<br />bar</h1>` results in `# foobar`, but it should probably be `# foo bar`. Example 2: `<td>foo<br />bar</td>` results in ` foobar |`, but it should be ` foo bar |`. I need to find where `<br>` tags are handled in `markdownify/main.py` (most likely) and ensure they result in a space when in an inline context. Plan: 1. Explore `markdownify/main.py` to find the `<br>` handler. 2. Create a reproduction script to confirm the bug. 3. Modify the `<br>` handler to add a space in inline contexts. 4. Verify the fix with the reproduction script and existing tests. Let's start by exploring the code.

I found it!

if '_inline' in parent_tags:
return ""
if self.options['newline_style'].lower() == BACKSLASH:
return '\\\\\\n'
else:
return ' \\n'
```
In `convert_br`, if `_inline` is in `parent_tags`, it returns an empty string. The problem statement says it should return a separating space.
Wait, if I change it to return `" "`, will it introduce double spaces or something?
The problem says:
`<h1>foo<br />bar</h1>` -> `# foobar` (currently)
If I change it to:
`# foo bar`
Let's verify with a reproduction script.

Confirmed. Both are consolidating `foo` and `bar`. Now I should check if returning `" "` is enough. Wait, what if the content already has spaces? `<h1>foo <br /> bar</h1>` If `convert_br` returns `" "`, it might become `# foo bar`. But standard markdown conversion often collapses whitespace or handles this in a way that one space is acceptable. Let's look at how others handle this. Usually, a `<br>` in an inline context is treated as a space unless it's a hard line break. If I return `" "`, then `<h1>foo<br />bar</h1>` becomes `# foo bar`. If I return `" "`, then `<h1>foo <br /> bar</h1>` becomes `# foo bar`. Is there any other way this is handled? Let's look at the `MarkdownConverter.convert` method and how it calls `convert_br`. I'll read more of `markdownify/__init__.py`.

I see multiple other `convert_*` methods that do this:
```python
def convert_blockquote(self, el, text, parent_tags):
# ...
if '_inline' in parent_tags:
return ' ' + text + ' '
# ...
def convert_div(self, el, text, parent_tags):
if '_inline' in parent_tags:
return ' ' + text.strip() + ' '
# ...
def convert_dd(self, el, text, parent_tags):
# ...
if '_inline' in parent_tags:
return ' ' + text + ' '
# ...
```
It seems that when an element is in an inline context, `markdownify` often adds surrounding spaces to ensure separation.
For `convert_br`, the current implementation is:
```python
def convert_br(self, el, text, parent_tags):
if '_inline' in parent_tags:
return ""
```
If I change this to `return " "`, it should resolve the issue.
Wait, let me double check if `convert_br` should return `" "` or `' ' + text + ' '`.
Wait, `convert_br`'s `text` argument is usually empty because `<br />` is a void element.
Let's verify if `text` is ever non-empty for `convert_br`.
A `<br>` tag has no children.
If I return `" "`, then `foo<br />bar` becomes `foo bar`.
If I return `" "`, it might be too many.
One thing to consider: if we have `foo<br /><br />bar`, it would become `foo bar` (two spaces). Which is probably fine.
Let's check if there are any existing tests for `<br>` in inline contexts.

Look at `tests/test_conversions.py:195`:
`assert md('<h3>A <br>B</h3>', heading_style=ATX) == '\\n\\n### A B\\n\\n'`
This test is ALREADY expecting a space! Wait, if it's already passing, then why the bug report?
Wait, notice the input: `<h3>A <br>B</h3>`. There is a space BEFORE the `<br>`.
If the output is `### A B`, and there was a space before `<br>`, then `<br>` itself was converted to an empty string.
`'A '` + `''` + `'B'` = `'A B'`.
The bug report says:
`md('<h1>foo<br />bar</h1>')` -> `# foobar` (no space)
In the test case:
`md('<h3>A <br>B</h3>')` -> `### A B` (space because of input)
So if I change `<br/>` to return `" "`, then:
`<h1>foo<br />bar</h1>` -> `# foo bar` (Correct)
`<h3>A <br>B</h3>` -> `### A B` (Two spaces!)
Hmm. Is two spaces acceptable in Markdown? Yes, but maybe it's not desired.
However, if `<br>` is treated as a space, then `foo <br> bar` should probably be `foo bar` or collapsed.
Let's check if `markdownify` usually collapses whitespace.
In `_convert_hn`:
`text = re_all_whitespace.sub(' ', text)`
But `_convert_hn` is called for the whole heading content.
Wait, if `convert_br` is called, it's part of the recursive conversion.
Let's see how `markdownify` handles inline tags in general.
Actually, if I want it to be a "separating space", maybe it should only add a space if there isn't one already? No, that's too complex for `convert_br` because it doesn't know the surrounding text easily.
Actually, if we look at how `convert_div` does it:
`return ' ' + text.strip() + ' '`
It adds spaces on both sides.
But `<br>` is different. It doesn't have "text" inside it.
If the goal is "separating space", then `" "` is the most logical return value.
Let's see what happens if I use `" "` and run the existing tests.
Actually, let's look at `test_conversions.py:195` again.
`assert md('<h3>A <br>B</h3>', heading_style=ATX) == '\\n\\n### A B\\n\\n'`
If I change `convert_br` to return `" "`, this test will fail because it'll be `### A B`.
Wait, let me check the actual code of `_convert_hn` again.
```python
def _convert_hn(self, n, el, text, parent_tags):
# ...
style = self.options['heading_style'].lower()
text = text.strip()
if style == UNDERLINED and n <= 2:
line = '=' if n == 1 else '-'
return self.underline(text, line)
text = re_all_whitespace.sub(' ', text)
# ...
```
Ah! `text = re_all_whitespace.sub(' ', text)`.
`re_all_whitespace` probably replaces `\s+` with a single space.
If so, `### A B` will become `### A B`.
Let's check what `re_all_whitespace` is.

`re_all_whitespace = re.compile(r'[\t \r\n]+')`
Yes, it replaces any sequence of whitespace characters with a single space (when used in `re_all_whitespace.sub(' ', text)`).
So for `<h3>A <br>B</h3>`, if `<br>` becomes `" "`, the text becomes `"A B"`, and `re_all_whitespace.sub(' ', "A B")` becomes `"A B"`. The test will still pass.

`convert_td` does:
`return ' ' + text.strip().replace("\n", " ") + ' |' * colspan`
It replaces `\n` with `" "`. But `<br>` in an inline context currently returns `""`. So `foo<br />bar` becomes `foobar`. If it becomes `foo bar`, the result is ` foo bar |`.
If I change `convert_br` to return `" "`, it'll work for `<td>` too. And since `convert_td` replaces `\n` with `" "`, it seems consistent.
Wait, what if `convert_br` returns `" "` and it's NOT in an inline context? It's already handled:
```python
def convert_br(self, el, text, parent_tags):
if '_inline' in parent_tags:
return ""
if self.options['newline_style'].lower() == BACKSLASH:
return '\\\\\\n'
else:
return ' \\n'
```
The `_inline` check is first.
Wait, if I change it to:
```python
def convert_br(self, el, text, parent_tags):
if '_inline' in parent_tags:
return " "
```
Then `<br>` in inline context becomes a space.

Everything seems to be working.
Let's double check for any other possible `_inline` usages of `convert_br` that might be affected.
The code for `convert_br` is:
```python
def convert_br(self, el, text, parent_tags):
if '_inline' in parent_tags:
return " "
if self.options['newline_style'].lower() == BACKSLASH:
return '\\\\\\n'
else:
return ' \\n'
```
The `_inline` tag is used to denote that the element is inside an inline context.
In the original code it returned `""`. Now it returns `" "`.
This matches the requirement: "`<br/>` in inline contexts (such as headings and table cells) evaluates to an empty string instead of a separating space".
Wait, I should check if there are other tags that also use `_inline` and how they handle it.
Looking at `convert_blockquote`, `convert_div`, `convert_dd`, `convert_dt`:
- `convert_blockquote`: `return ' ' + text + ' '`
- `convert_div`: `return ' ' + text.strip() + ' '`
- `convert_dd`: `return ' ' + text + ' '`
- `convert_dt`: `return ' ' + text + ' '`
They all seem to add spaces around the content if `_inline` is present.
`convert_br` is a bit different because it doesn't have "text" content usually (it's a void element).
One detail: in `convert_td`, it does:
```python
def convert_td(self, el, text, parent_tags):
colspan = 1
if 'colspan' in el.attrs and el['colspan'].isdigit():
colspan = int(el['colspan'])
return ' ' + text.strip().replace("\n", " ") + ' |' * colspan
```
The `text` passed to `convert_td` is the result of converting its children.
If `td` contains `foo<br />bar`, the children are `foo` (Text), `<br />` (Tag), `bar` (Text).
The `convert_br` method is called for the `<br />` tag.
If `convert_br` returns `" "`, the resulting `text` for `td` will be `foo bar`.
Then `convert_td` will strip it and return ` foo bar |`.
Wait, what if I have `foo<br /><br />bar`?
It would become `foo bar`.
What if I have `<h1 >foo<br />bar</h1>`?
The `_convert_hn` method:
```python
def _convert_hn(self, n, el, text, parent_tags):
""" Method name prefixed with _ to prevent <hn> to call this """
if '_inline' in parent_tags:
return text
# ...
text = re_all_whitespace.sub(' ', text)
# ...
```
`re_all_whitespace` replaces multiple whitespaces with a single space.
So `foo bar` becomes `foo bar`.
Thus `# foo bar` is correct.
One more check on the problem statement:
`print(repr(md('<h1>foo<br />bar</h1>'))) # '# foobar'` (before)
`print(repr(md('<td>foo<br />bar</td>'))) # ' foobar |'` (before)
My results now:
`'# foo bar'`
`' foo bar |'`
This looks correct.
Let's verify if there are any other `convert_br` calls.
grep showed:
`markdownify/__init__.py:444: def convert_br(self, el, text, parent_tags):`
Is it possible that `convert_br` is overridden in some subclasses?
`MarkdownConverter` is the main class.
I don't see any other classes overriding it.
Final check on the diff.

The diff is minimal and correct.
One last check: what if `_inline` is not in `parent_tags`?
Then it returns `\\n` or ` \\n` (depending on `newline_style`). This is correct for block-level `<br>`.
What about `tests/test_conversions.py:195: assert md('<h3>A <br>B</h3>', heading_style=ATX) == '\\n\\n### A B\\n\\n'`?
Wait, if the existing test already says `A B`, why was the bug reported?
Let's look at that test:
`assert md('<h3>A <br>B</h3>', heading_style=ATX) == '\\n\\n### A B\\n\\n'`
In this case, there are spaces around `<br>`: `A <br>B`.
So the output was `A B` (two spaces), which `_convert_hn` then collapsed to `A B` using `re_all_whitespace.sub(' ', text)`.
But if the HTML is `foo<br />bar` (no spaces), it would have been `foobar`.
Let's verify this.

I have successfully reproduced the bug, implemented the fix, and verified it with the reproduction case and existing tests. Summary: Modified `markdownify/__init__.py` in `convert_br` to return a single space `" "` instead of an empty string `""` when `_inline` is in `parent_tags`. This ensures that `<br />` behaves as a separating space in inline contexts like headings and table cells.
Turn 24at 359 s
The `<br/>` tag in inline contexts (such as headings and table cells) was previously converting to an empty string, leading to words being joined together.

Confirmed. Both are consolidating `foo` and `bar`. Now I should check if returning `" "` is enough. Wait, what if the content already has spaces? `<h1>foo <br /> bar</h1>` If `convert_br` returns `" "`, it might become `# foo bar`. But standard markdown conversion often collapses whitespace or handles this in a way that one space is acceptable. Let's look at how others handle this. Usually, a `<br>` in an inline context is treated as a space unless it's a hard line break. If I return `" "`, then `<h1>foo<br />bar</h1>` becomes `# foo bar`.

I see multiple other `convert_*` methods that do this:
```python
def convert_blockquote(self, el, text, parent_tags):
# ...
if '_inline' in parent_tags:
return ' ' + text + ' '
# ...
def convert_div(self, el, text, parent_tags):
if '_inline' in parent_tags:
return ' ' + text.strip() + ' '
# ...
def convert_dd(self, el, text, parent_tags):
# ...
if '_inline' in parent_tags:
return ' ' + text + ' '
# ...
```
It seems that when an element is in an inline context, `markdownify` often adds surrounding spaces to ensure separation.
For `convert_br`, the current implementation is:
```python
def convert_br(self, el, text, parent_tags):
if '_inline' in parent_tags:
return ""
```
If I change this to `return " "`, it should resolve the issue.
Wait, let me double check if `convert_br` should return `" "` or `' ' + text + ' '`.
Wait, `convert_br`'s `text` argument is usually empty because `<br />` is a void element.
Let's verify if `text` is ever non-empty for `convert_br`.
A `<br>` tag has no children.
If I return `" "`, then `foo<br />bar` becomes `foo bar`.
If I return `" "`, it might be too many.
One thing to consider: if we have `foo<br /><br />bar`, it would become `foo bar` (two spaces). Which is probably fine.
Let's check if there are any existing tests for `<br>` in inline contexts.

Look at `tests/test_conversions.py:195`:
`assert md('<h3>A <br>B</h3>', heading_style=ATX) == '\\n\\n### A B\\n\\n'`
This test is ALREADY expecting a space! Wait, if it's already passing, then why the bug report?
Wait, notice the input: `<h3>A <br>B</h3>`. There is a space BEFORE the `<br>`.
If the output is `### A B`, and there was a space before `<br>`, then `<br>` itself was converted to an empty string.
`'A '` + `''` + `'B'` = `'A B'`.
The bug report says:
`md('<h1>foo<br />bar</h1>')` -> `# foobar` (no space)
In the test case:
`md('<h3>A <br>B</h3>')` -> `### A B` (space because of input)
So if I change `<br/>` to return `" "`, then:
`<h1>foo<br />bar</h1>` -> `# foo bar` (Correct)
`<h3>A <br>B</h3>` -> `### A B` (Two spaces!)
Hmm. Is two spaces acceptable in Markdown? Yes, but maybe it's not desired.
However, if `<br>` is treated as a space, then `foo <br> bar` should probably be `foo bar` or collapsed.
Let's check if `markdownify` usually collapses whitespace.
In `_convert_hn`:
`text = re_all_whitespace.sub(' ', text)`
But `_convert_hn` is called for the whole heading content.
Wait, if `convert_br` is called, it's part of the recursive conversion.
Let's see how `markdownify` handles inline tags in general.
Actually, if I want it to be a "separating space", maybe it should only add a space if there isn't one already? No, that's too complex for `convert_br` because it doesn't know the surrounding text easily.
Actually, if we look at how `convert_div` does it:
`return ' ' + text.strip() + ' '`
It adds spaces on both sides.
But `<br>` is different. It doesn't have "text" inside it.
If the goal is "separating space", then `" "` is the most logical return value.
Let's see what happens if I use `" "` and run the existing tests.
Actually, let's look at `test_conversions.py:195` again.
`assert md('<h3>A <br>B</h3>', heading_style=ATX) == '\\n\\n### A B\\n\\n'`
If I change `convert_br` to return `" "`, this test will fail because it'll be `### A B`.
Wait, let me check the actual code of `_convert_hn` again.
```python
def _convert_hn(self, n, el, text, parent_tags):
# ...
style = self.options['heading_style'].lower()
text = text.strip()
if style == UNDERLINED and n <= 2:
line = '=' if n == 1 else '-'
return self.underline(text, line)
text = re_all_whitespace.sub(' ', text)
# ...
```
Ah! `text = re_all_whitespace.sub(' ', text)`.
`re_all_whitespace` probably replaces `\s+` with a single space.
If so, `### A B` will become `### A B`.
Let's check what `re_all_whitespace` is.
Look at `tests/test_conversions.py:195`:
`assert md('<h3>A <br>B</h3>', heading_style=ATX) == '\\n\\n### A B\\n\\n'`

`convert_td` does:
`return ' ' + text.strip().replace("\n", " ") + ' |' * colspan`
It replaces `\n` with `" "`. But `<br>` in an inline context currently returns `""`. So `foo<br />bar` becomes `foobar`. If it becomes `foo bar`, the result is ` foo bar |`.
If I change `convert_br` to return `" "`, it'll work for `<td>` too. And since `convert_td` replaces `\n` with `" "`, it seems consistent.

Everything seems to be working.
Let's double check for any other possible `_inline` usages of `convert_br` that might be affected.
The code for `convert_br` is:
```python
def convert_br(self, el, text, parent_tags):
if '_inline' in parent_tags:
return " "
if self.options['newline_style'].lower() == BACKSLASH:
return '\\\\\\n'
else:
return ' \\n'
```
The `_inline` tag is used to denote that the element is inside an inline context.
In the original code it returned `""`. Now it returns `" "`.
This matches the requirement: "`<br/>` in inline contexts (such as headings and table cells) evaluates to an empty string instead of a separating space".
Wait, I should check if there are other tags that also use `_inline` and how they handle it.
Looking at `convert_blockquote`, `convert_div`, `convert_dd`, `convert_dt`:
- `convert_blockquote`: `return ' ' + text + ' '`
- `convert_div`: `return ' ' + text.strip() + ' '`
- `convert_dd`: `return ' ' + text + ' '`
- `convert_dt`: `return ' ' + text + ' '`
They all seem to add spaces around the content if `_inline` is present.
`convert_br` is a bit different because it doesn't have "text" content usually (it's a void element).
One detail: in `convert_td`, it does:
```python
def convert_td(self, el, text, parent_tags):
colspan = 1
if 'colspan' in el.attrs and el['colspan'].isdigit():
colspan = int(el['colspan'])
return ' ' + text.strip().replace("\n", " ") + ' |' * colspan
```
The `text` passed to `convert_td` is the result of converting its children.
If `td` contains `foo<br />bar`, the children are `foo` (Text), `<br />` (Tag), `bar` (Text).
The `convert_br` method is called for the `<br />` tag.
If `convert_br` returns `" "`, the resulting `text` for `td` will be `foo bar`.
Then `convert_td` will strip it and return ` foo bar |`.
Wait, what if I have `foo<br /><br />bar`?
It would become `foo bar`.
What if I have `<h1 >foo<br />bar</h1>`?
The `_convert_hn` method:
```python
def _convert_hn(self, n, el, text, parent_tags):
""" Method name prefixed with _ to prevent <hn> to call this """
if '_inline' in parent_tags:
return text
# ...
text = re_all_whitespace.sub(' ', text)
# ...
```
`re_all_whitespace` replaces multiple whitespaces with a single space.
So `foo bar` becomes `foo bar`.
Thus `# foo bar` is correct.
One more check on the problem statement:
`print(repr(md('<h1>foo<br />bar</h1>'))) # '# foobar'` (before)
`print(repr(md('<td>foo<br />bar</td>'))) # ' foobar |'` (before)
My results now:
`'# foo bar'`
`' foo bar |'`
This looks correct.
Let's verify if there are any other `convert_br` calls.
grep showed:
`markdownify/__init__.py:444: def convert_br(self, el, text, parent_tags):`
Is it possible that `convert_br` is overridden in some subclasses?
`MarkdownConverter` is the main class.
I don't see any other classes overriding it.
Final check on the diff.

Let's look at that test:
`assert md('<h3>A <br>B</h3>', heading_style=ATX) == '\\n\\n### A B\\n\\n'`

Wait, if the existing test already says `A B`, why was the bug reported?
Let's look at that test:
`assert md('<h3>A <br>B</h3>', heading_style=ATX) == '\\n\\n### A B\\n\\n'`
In this case, there are spaces around `<br>`: `A <br>B`.
So the output was `A B` (two spaces), which `_convert_hn` then collapsed to `A B` using `re_all_whitespace.sub(' ', text)`.
But if the HTML is `foo<br />bar` (no spaces), it would have been `foobar`.
Let's verify this.

def md(html, **options):
return MarkdownConverter(heading_style="ATX").convert(html)

Wait, I am running this AFTER my fix. Let me check the original code again. Ah, the original code had `return ""`. So `foo<br />bar` became `foobar`. And `foo <br /> bar` became `foo bar` which became `foo bar`. Exactly. Everything is consistent.
