I'll note CSS specs explicitly allow making the ancestors of the
activated element to also match :active.

FWIW, I think the behavior currently in the spec makes the most sense.
If the element has no behavior to activate, it doesn't make sense to
me for the element to ever match :active. And if there is behavior to
activate, it should be keyboard-activateable as well, not just mouse-
I'm also interested to know whether there's a web-compat issue here or
just a bug-compat issue, and what the implementers think.
