Natively 4:3 aspect ratio videos on Youtube get cropped out of the player

As the title says. Going fullscreen or into theater mode will show the full video.

The video also gets cropped/shifted to the right when using the miniplayer function, and as a side issue the extension options don't seem to affect the miniplayer at all (for what it's worth).

It works fine for me even in normal player.

The "issue with video escaping the player" — this if I understand right:

Can be fixed by adding the following to the Advanced settings -> Additional CSS for this site while on youtube:

#movie_player {
  overflow: hidden !important;
}

Not the type of "escaping" I meant, I'll show you in the video attached.

I also found what causes the issue for me: I normally have youtube on 110% zoom (not a fan of the wasted space on the side), and apparently "that" paired with the presence of the toolbar (hiding it doesn't cause the sliding to the right) is what causes the wrong crop.

And that's part of the reason the big UI rework that's coming eventually will only work in full screen by default (and in theater mode in select few sites that have it), but not in normal players unless explicitly enabled.
