[whatwg] Allowing custom attributes on <html> or <body> in documents for media resources

Can we allow the UA to add custom vendor-prefixed attributes to the <html>
and/or <body> elements? Alternatively, a vendor-prefixed class? We want to
be able to use a style sheet with rules matching custom attributes to
indicate various situations (e.g., whether the document is a toplevel
browsing context) to set the viewport background.

"If we claim to be without sin, we deceive ourselves and the truth is not
in us. If we confess our sins, he is faithful and just and will forgive us
our sins and purify us from all unrighteousness. If we claim we have not
sinned, we make him out to be a liar and his word is not in us." [1 John
1:8-10]
