Andreas Kling	4b3abc6958	LibWeb: Move invalidation set matching into a helper ... Element.cpp still contained the CSS logic for deciding whether an invalidation set references features present on an element. Move that matcher into CSS::Invalidation::InvalidationSetMatcher. The helper uses Element's public API for classes, id, attributes, pseudo-class state, and removed-attribute tracking. This keeps Element focused on DOM state while CSS::Invalidation owns selector feature matching.	2026-04-29 15:47:23 +02:00
Andreas Kling	ea64c5e147	LibWeb: Move :has() mutation checks into a helper ... Node.cpp currently knows too much about selector invalidation metadata when deciding whether subtree mutations can affect :has() selectors. Pull that logic into CSS/Invalidation/HasMutationFeatureCollector so DOM mutation code can ask a focused helper instead of inspecting StyleInvalidationData directly. This is a behavior-preserving extraction. It keeps the existing conservative fallbacks for featureless subtree-sensitive selectors and still uses the existing element property matching helper for pseudo-class metadata.	2026-04-29 15:47:23 +02:00
