Breaking change

Proposed change

Disable flaky knx tests that fail due to the Python 3.14.3 asyncio executor scheduling change (#162263).

The following tests are affected:

• tests/components/knx/test_sensor.py::test_sensor_restore

These tests are skipped with @pytest.mark.xfail until codeowners can address the underlying timing issue. A tracking issue has been created for this: #169081.

Type of change

• Dependency upgrade

• New feature (which adds functionality to an existing integration)
• Deprecation (breaking change to happen in the future)
• Breaking change (fix/feature causing existing functionality to break)
• Code quality improvements to existing code or addition of tests
