Works well. It does not quite "disable" features like fullscreen (at lease for me). Rather the ui for those controls is zoomed in/cropped so you cant click them, but the video itself is fine. Simply right clicking the video player gives me access to those controls like fullscreen, cinema view, playback speed, etc.

Also on firefox, you can click the pop out icon to create a new player window which has its own fullscreen/time bar controls
