Re: [csswg-drafts] [css-pseudo] clarify paired-cascading behavior (#6386)

@delan Wrt which origins disable UA defaults, I'm OK with @emilio's answer as well. Though including the Transitions origin seems weird to me, what if the UA rules want to transition between two styles? That'll still end up in the Transitions origin. Wrt unset/revert, the logic proposed makes sense to me.

UA cannot do these weird things when the author has specified colors. They have to use the author-specified colors with no modification. But when using UA-chosen colors, they can choose anything.

Run a search for "Firefox userContent.css".
