This moves the panel down below the player:

.video-js .vjs-control-bar {
position: static;
visibility: visible;
}

Stylus or Violentmonkey

Example

Implementation for youtube.com/ here: https://gf.zukizuki.org/en/scripts/11485-youtube-ui-fix

Solution :

.video-js .vjs-control-bar {
position: static;
visibility: visible;
opacity :1!important;
}

But in the full screen version, the elements move to the ceiling.
