Log Message:
-----------
[:has()] scope selector matching unnecessarily returns documentElement() on
failure

Reviewed by Alan Baradlay.
When no ancestor matches any ruleset's scope selector and no ruleset is
scope-breaking, no :has() bearer can be affected by the change. Return
null and skip invalidation instead of falling back to documentElement.
This fallback isn't reached in practice today. It's a guard for future
changes that thread scope selectors through more invalidation paths.
