I think the backspace thing matters more than spacebar, because spacebar isn't going to cause you to lose (potentially hours of) work.

I do find the spacebar behavior isn't super predictable when I am trying to pause things, such as youtube .

The most confusing thing is that Youtube and Netflix seem to occasionally toggle pause when you press space; other times Youtube scrolls, and Netflix does nothing (there'd be nowhere to scroll).

I've never managed to consistently replicate it by having had the player in/out of focus already, not/scrolled, etc. odd.

It's YouTube specific, but "k" is more reliable for me as a pause/unpause button on YouTube.

Chrome is lately behaving even more unpredictably when scrolling with the spacebar, because now if you click on either the back or forward buttons it puts a focus rectangle on them and now pressing space will go back/forward again instead of scrolling down like I wanted.
