When using smaller tracks, it would be aesthetically pleasing if all toggle buttons were lined up.

I tried patching this myself. Current behaviour on the left, wishlist on the right.

The easiest way I found to do this was to just add the toggleVideo button, but disable it. Ideally it should be an empty area the size of a button, but this might be easier for a track to switch between an "audio" => "video" => "audio" type track, which currently doesn't provide any visual feedback.
