Description Fernando Marcelino Muniz 2026-06-07 16:40:29 UTC 
STEPS TO REPRODUCE
1. Have an app with media (music/video).
2. Hover over the app on the Panel.
3. Click the volume button to un/mute it.

OBSERVED RESULT
The window preview disappears even though the cursor is still over the app.

EXPECTED RESULT
Interacting with the un/mute button shouldn't cause the app's window preview to disappear.

Comment 1 Fernando Marcelino Muniz 2026-06-07 16:42:37 UTC 
Usually it disappears because clicking on the app would bring it into view, therefore not needing the window preview.
But the un/mute button doesn't bring the app into view, so the window preview should remain there.

Can confirm. Could use polishing.
