Just walk the DOM instead. This will be slower, but I'm going to get rid of the global RuleFeatureSet anyway, so this is just a temporary measure to simplify the system. Removing the set also means removing a bunch of special cases for when the document didn't have any ShadowRoots with styles (which is very unlikely in Sky).
