I did a local build with this patch, but I still managed to trigger the
issue. It seems to be a bit easier to trigger by switching quality
settings using the gear icon in YouTube videos *after* having entered
fullscreen.

I am doing now one more build with both this and your other suggested
patch to see what happens :)
