Consider all the pseudo-classes in a given compound selector when computing restyle hints, not just the rightmost one.

Browse source 
For some reason when I wrote this code I mixed up the rules for pseudo-elements
(rightmost, maximum of one) with those of pseudo-classes (which have no such
restriction). This caused a correctness issue which can be demonstrated with the
associated reftest modification.
