Skip ruleset invalidations for SubtreeStyleChange roots.
When the TreeScope invalidation root is already with SubtreeStyleChange
there is no need to schedule ruleset invalidations for that scope. We
did not end up scheduling the invalidation sets, but went through a lot
of unnecessary steps in scheduleInvalidationsForRuleSets(). Instead,
just return early.
Added some more tests and corrected typos from
