MatplotlibDeprecationWarning running Testing with PythonDebugger #1727
Description
Type: Bug
Behaviour
I am getting MatplotlibDeprecationWarning that causes an error with test_warn failed when I run this test with the PythonDebugger in the Testing extension.
versions:
pytest==8.3.1
matplotlib==3.9.2
Steps to reproduce:
import warnings
import pytest
def f():
warnings.warn("Test", UserWarning)
def test_warn():
with pytest.warns(UserWarning, match="Test"):
f()Setting a breakpoint in the line of with pytest.warns(UserWarning, match="Test"): and run in debug-mode. The debugger raises an error:

I would have expected not to see this warning and be able to continue with the debugging.
Running the test with Testing without debug points or running the tests with pytest on the terminal works just fine.
