Adaptive Probe Volumes tab in Lighting window shows stale "URP Asset does not support APV" warning after exiting Play Mode

Steps to reproduce:

1. Create a new URP project
2. Open the Lighting window (Window > Rendering > Lighting)
3. Switch to "Adaptive Probe Volumes" tab
4. Click "Open" and change "Light Probe System" to "Adaptive Probe Volumes"
5. With Adaptive Probe Volumes tab visible enter Play mode
6. Exit Play mode
7. Without hovering over the Lighting tab, observe the Adaptive Probe Volumes tab

Actual results: The Adaptive Probe Volumes tab incorrectly displays the warning "The current URP Asset does not support Adaptive Probe Volumes". The stale warning persists until the mouse cursor enters the Lighting window, at which point the tab repaints and the warning disappears

Expected results: The Adaptive Probe Volumes tab does not change after exiting the Play mode and no warning is shown
