logging.captureWarnings(True) doesn't show object allocation (-X tracemalloc)

Bug report

When using logging.captureWarnings(True), the information about object allocation that you should get with -X tracemalloc gets lost.

It appears to be a discrepancy between Python and C implementation of the warnings module? source isn't passed to the created WarningMessage object in the Lib/warnings.py:
https://github.com/python/cpython/blob/a17cd47b614f8bc660788647a009a25e121221d7/Lib/warnings.py#L12
https://github.com/python/cpython/blob/a17cd47b614f8bc660788647a009a25e121221d7/Lib/warnings.py#L17
https://github.com/python/cpython/blob/a17cd47b614f8bc660788647a009a25e121221d7/Lib/warnings.py#L394
while it is in Python/_warnings.c:
https://github.com/python/cpython/blob/a17cd47b614f8bc660788647a009a25e121221d7/Python/_warnings.c#L593-L605

Reproduction steps:

1. Create a file repro.py with contents:

import logging
import tempfile
import warnings

warnings.simplefilter("default", category=ResourceWarning)
logging.basicConfig()


print("--- UNCAPTURED WARNING ---")
file = tempfile.SpooledTemporaryFile(1)
file.write(b"foo")
file = None

print("\n--- CAPTURED WARNING ---")
logging.captureWarnings(True)
file = tempfile.SpooledTemporaryFile(1)
file.write(b"foo")
file = None

2. Run python -X tracemalloc=5
3. See that output only contains object allocation traceback for uncaptured warning:

--- UNCAPTURED WARNING ---
/tmp/test_tracemallo/repro.py:12: ResourceWarning: unclosed file <_io.BufferedRandom name=3>
  file = None
Object allocated at (most recent call last):
  File "/tmp/test_tracemallo/repro.py", lineno 11
    file.write(b"foo")
  File "/usr/lib/python3.10/tempfile.py", lineno 911
    self._check(file)
  File "/usr/lib/python3.10/tempfile.py", lineno 807
    self.rollover()
  File "/usr/lib/python3.10/tempfile.py", lineno 812
    newfile = self._file = TemporaryFile(**self._TemporaryFileArgs)
  File "/usr/lib/python3.10/tempfile.py", lineno 760
    return _io.open(fd, mode, buffering=buffering,

--- CAPTURED WARNING ---
WARNING:py.warnings:/tmp/test_tracemallo/repro.py:18: ResourceWarning: unclosed file <_io.BufferedRandom name=3>
  file = None

Compara la construcción de WarningMessage en Lib/warnings.py con el tratamiento correspondiente en Python/_warnings.c y ejecuta el comando repro.py proporcionado con -X tracemalloc=5. Se considera completado cuando las advertencias redirigidas mediante logging.captureWarnings(True) conservan el traceback de asignación del objeto que se muestra para las advertencias no capturadas.
