Web (Firefox): exit fullscreen button fails with NoSuchMethodError: webkitExitFullscreen is not a function

[marcolvz]

Description

On the web build running in Firefox, the player's exit-fullscreen button does nothing. Entering fullscreen via the button works correctly, but exiting via the same button fails (the video stays fullscreen) and throws an uncaught error in the console. Pressing ESC exits fullscreen normally.

Expected behavior
Clicking the exit-fullscreen button exits fullscreen, as it does when entering.

Actual behavior
The button does nothing and the console logs:
Uncaught : NoSuchMethodError: method not found: 'webkitExitFullscreen' (q.webkitExitFullscreen is not a function)

Browser: Firefox 152.0.4 (64-bit)

Reproduction steps

1. Open Fladder web in Firefox
2. Start playback of any item
3. Enter fullscreen using the player's fullscreen button → works
4. Click the fullscreen button again to exit → nothing happens
5. Open the browser console → an uncaught error is logged
6. Press ESC → exits fullscreen as expected
