Make style updates reach a fixed point when slot invalidation dirties assigned nodes after their traversal point. During inherited-style cascades, only the topmost changed element scans for descendant slots. Animation inherited-style updates now include the target slot and walk shadow-including descendants, so host animations propagate inherited values through shadow trees and assigned slottables. Animated inherited longhands also carry the same inherited-style invalidation signal as regular style changes. Mark custom elements dirty when their :defined state flips, so upgraded elements do not keep stale :not(:defined) computed style. Add coverage for slotted menu invalidation, descendant-slot scan counts, target slot animations, host shadow-tree animations, and explicit inherit from an animated non-inherited longhand.
