Tests fail with pytest-asyncio>=0.25.0 #5511
Description
Tested with textual version 1.0.0 and python version 3.12.8
When updating pytest-asyncio to from 0.24.0 to 0.25.0, some tests start failing:
=========================== short test summary info ============================

ERROR tests/test_focus.py::test_focus_next_and_previous_with_str_selector_without_self - RuntimeError: There is no current event loop in thread 'MainThread'.Re-running just the failed tests makes them pass, to reproduce this you need to run the whole test suite or at least a larger part.
