Description

On niri, when setting an application to fullscreen, the "Keeping Awake" function does simply not keep it awake. Tested with a gamescope-window and loupe.

Expected Behavior

When "Keeping Awake" is enabled, the monitor should stay on regardless of inactivity, including when applications are in fullscreen.

Steps to Reproduce

1. Under "Idle Settings" set "Turn off monitors after" to 15 seconds.
2. Toggle "Keeping Awake" on under the quick menu or via ipc call.
3. Open any application (e.g: loupe) in fullscreen
4. Wait for 15 seconds.
