Youtube shorts layout is broken you can't see the progress bar since around 13 days ago.

===

The sidebar is often leaving a white area of blank space behind when it retracts. This often happens when the window is resized but also at other times.

This telegraphs a low quality product.

The sidebar is taking far too long to retract after the mouse cursor is moved outside of the sidebar area. I recommend 20ms as opposed to the current delay of roughly 1 second.

This is tying me up, waiting for it to retract very often as many online applications are using this area for their own sidebars.

The Spotify icon in the sidebar, whilst hovering, displays track and artist names as well as transport controls rw, play/pause and ff.

These are not working if an ad is playing and will not pause the ad or set pause once the ad is finished.

I may add more to this post because the settings menu is very, very confusing and there are in fact mistakes.

I'm an experienced UI designer and developer.
