UI bug in Edge Stable and Edge Canary for android.

I'm currently using Edge Canary on Samsung Tab S9 +. There is a serious UI bug. Whenever I exit any video from fullscreen mode, layout of browser changes completely.

 I have attached two pictures for reference. In picture 1 , a youtube video is clicked and playing normally.

After I click go fullscreen and I come back again to the normal player mode, layout changes completely and new buttons appear at the bottom. This looks horrendous on a tab. Otherwise Edge compatibility is very good for an android tablet . I'dlike to add that this is not specifc to youtube. This happens every time I go fullscreen and exit back from any video on any site. So this is a problem with edge, not with the website.

I checked stable and canary versions. This would be in dev as well though i havent checked.
