The original bug says

Mouse cursor doesnt automatically disappear when entering fullscreen

which might be the more significant issue here? Let's have a look at both.

I collected a profile for this case https://share.firefox.dev/42RiFTY, so from the moment that we dispatched the fullscreenchange event to the point where the controls were hidden, it only took ~900ms, so indeed it was too fast.

hmm, what made youtube decide to hide them..
