[Selection and Copying Restorer] Breaks youtube interactions

[Quinten0508]

Enabling this script and playing any video will cause a large part of the youtube video UI to become unresponsive. This includes:

• Clicking on the video player to play/pause
• Clicking on or dragging the progress bar
• Clicking on any of the buttons on the bottom of the video player (mute, volume, settings, captions, etc) except for play/pause
• Using any of the keyboard shortcuts (arrow keys, jkl, etc)

Using Librewolf (a Firefox fork) version 126.0.1, but this has been happening for a while - only just now narrowed it down to this specific userscript. Confirmed by disabling FF's own tracking protection and disabling all other extensions (private browsing window).

Only FF? No issue in Chrome / Edge?

Hadn't tested.
Just tried with Ungoogled Chromium, which seems to work fine. Used Violentmonkey for both browsers.
