videojs: video slider not right when finished playing in background

[infinite-persistence]

This one is super minor, but odd nonetheless since it is not in sync with the Time widget.

1. Disable "Autoplay" in the settings.
2. https://odysee.com/@davidpakman:7/another-covid-anti-vaxxer-comes-back-for:5
3. Fully play the file to get all the blobs (not sure if it matters, though). You can use x2 speed.
4. After the video is done, click at 5:58 and play. Move to another tab (non-Odysee) and wait until you hear the end of the video.
5. Return to the video tab: the slider should be at the end instead of restored to the location when I changed to another tab. The time widget is showing the end, though.

I think I remember seeing a bug on in video.js's repo about this behavior.
