Fullscreen mode persists after exiting playback via Back button

[mrfoggg]

When watching a video in fullscreen mode, pressing the Back button (returning from the player to the main application interface) keeps the application window in fullscreen mode.

This behavior is unexpected and inconsistent with typical media player UX.

Steps to reproduce

1. Open any video
2. Switch to fullscreen mode
3. While still in fullscreen, press the Back button to exit playback
4. Observe that the main application UI remains in fullscreen

Expected behavior

• If fullscreen mode is not explicitly enabled in application settings, exiting the player should:
  • Return the window to windowed mode
  • Show the main UI in non-fullscreen state

Actual behavior

• Fullscreen window state persists after leaving the player

Why this is an issue

• Fullscreen is a playback-specific context, not a global application state
• Most media players exit fullscreen when playback ends or when the user leaves the player
• Current behavior may feel confusing, especially for users who expect fullscreen to apply only to video playback

Suggested solution

• On exiting the player (via Back button):
  • Automatically exit fullscreen mode unless fullscreen is enabled globally in settings
• Alternatively:
  • Distinguish between player fullscreen and application fullscreen
