`logging.captureWarnings` and `warnings.catch_warnings` do not play well together

Bug report

Bug description:

When logging.captureWarnings(True) is called within a warnings.catch_warnings(record=True) context warnings emitted during the context are not recorded.

import logging, warnings
with warnings.catch_warnings(record=True) as rec:
    logging.captureWarnings(True)
    warnings.warn("foo")
assert len(rec) == 1  # fails since len(rec) == 0

one work-around for this is to enable captureWarnings outside the context

import logging, warnings
logging.captureWarnings(True)
with warnings.catch_warnings(record=True) as rec:
    warnings.warn("foo")
assert len(rec) == 1

I tested the above examples on 3.10, 3.13 and 3.14.0b2.

However on 3.14.0b2 with PYTHON_CONTEXT_AWARE_WARNINGS=1 (to pull in the changes from https://github.com/python/cpython/pull/130010) the second example (enabling captureWarnings outside the catch_warnings) no longer works.

CPython versions tested on:

3.13

Operating systems tested on:

macOS

Commencez par reproduire les exemples avec logging.captureWarnings(True) et warnings.catch_warnings(record=True), y compris PYTHON_CONTEXT_AWARE_WARNINGS=1. Suivez l’interaction entre ces deux API et vérifiez que les avertissements émis dans le contexte sont enregistrés dans les deux configurations décrites par le rapport.
