The playlist turns into an infinite one when playing instead of the standard one

Concise Description

Using the plugin with all features disabled interferes with the standard playlist window, making it infinite instead of normal. This is very annoying with large playlists.

Use Chrome to reproduce the issue with all plugin features disabled, then open a video in a playlist and compare the standard playlist window with the reported infinite behavior. Trace the playlist-related extension entry point and confirm the fix by verifying that large playlists remain finite and behave normally.
