Only mark an element itself dirty for interaction pseudo-class changes when matching rules can plausibly match that element. Check every style scope observing the element, and keep the normal invalidation plan for descendants and siblings. Treat pseudo-elements as neutral during the plausibility check so rules like a:hover::before still invalidate the originating element. Add text coverage for non-matching hover rules and pseudo-element hover changes.
