Behavior of matches() and closest() with :scope()

In https://bugzilla.mozilla.org/show_bug.cgi?id=886308#c29 bz points
out that I introduced a regression relative to the old definition of
matches() with the new hook in Selectors.

I guess the way to fix this for matches() would be to add a :scope
elements argument. What about closest(), should it have that argument
too?

I'm not too familiar admittedly with what would be desirable here.
