> How many sites put invisible DOM elements over the videos?

A lot of them? Vimeo, for instance, has a number of opacity: 0 and hidden divs over the video. Twitch has at least a couple of opacity: 0 divs on top.

Maybe we're interpreting the phrase

> hidden empty div over YouTube videos

differently? That's the structure I assume they were talking about.

I'd assume that it was actually an invisible, but not technically hidden div, leading to a fully transparent blending pass - divs with opacity:0 or display:none are trivial to optimize for this case.

Considering that it's now optimized and that's not what the original post said, I don't know why you'd assume that.
