Is there a good reason why we're defining global custom properties on :root/html and not on body?

@matuzo cuz we think it's the top most node that will reach to all items in the page... but nope

i put mine on html instead of :root so they're easy to overwrite

there's been CSSWG chatter about a new location that would be true root and would be available to all elements AND pseudo elements. but it's not complete.

@argyleink that would also include ::backdrop, right?
@matuzo it would yep
