This does not happen on my end. I wonder why? I'm in Europe and using Firefox with tracking protection, Privacy Badger and uBlock Origin (and no cookie popup killers of any kind). No sign of youtube, and the native element functions properly.
EDIT: Tried also on Chrome. Accepted only essential cookies. No youtube. (Chrome also has uBlock Origin installed, though I don't know how effective that currently is.)
