Changing :active or :open used the broad style invalidation path, so large subtrees were recomputed even when only the target element and selector-matched relatives could be affected. Reuse the :has() feature collector to keep conservative fallback for observable :has() cases, then use pseudo-class property invalidation for the common targeted path.
