Better to watch the screencast:

Screencast.From.2026-08-09.15-28-39.mp4

But this also happens with other indicators, so I suppose this would be an issue of Wingpanel itself:

Screencast.From.2026-08-09.15-27-22.mp4

Steps to Reproduce

1. Open Applications Menu
2. Focus on the search entry in Grid View
3. Press ↓ to move focus to the app icons
4. Wait for a few seconds
5. See the focus are stolen i.e. the blue indication that has focus disappears

Expected Behavior

Focus on app icons should not be stolen as before in GTK 3 version of Applications Menu.
