Catching both warning and error, message of warning is ignored

[MarcoGorelli]

• a detailed description of the bug or problem you are having
• output of pip list from the virtual environment you are using
• pytest and operating system versions
• minimal example if possible

Here's a reproducible example:
t.py:

import warnings

def foo():
    warnings.warn('my warning message', FutureWarning)
    raise ValueError('my error message')

test_t.py:

import pytest

from t import foo

def test_foo():
    with (
        pytest.raises(ValueError, match='my error message'),
        pytest.warns(FutureWarning, match='definitely not my warning message'),
    ):
        foo()

Then:

(.venv) marcogorelli@DESKTOP-U8OKFP3:~/tmp$ pytest test_t.py

================================================== 1 passed in 0.00s ===================================================

I'd have expected it to error with something like

E       Failed: DID NOT WARN. No warnings of type (<class 'FutureWarning'>,) matching the regex were emitted.
E        Regex: definitely not my warning message
E        Emitted warnings: [FutureWarning('my warning message')]
