Once matching is supported in bug 1808228, the invalidation reftests in bug 1809470 will still fail (though the invalidation test added in bug 1809659 passes), so it should be addressed before enabling layout.css.nth-child-of.enabled by default in bug1808229.

Component::NthOf should be added to collect_ancestor_hashes(), maybe_allowed_after_pseudo_element(), matches_for_stateless_pseudo_element(), and specific_bucket_for() like Component::Is and Component::Where are, which perhaps gets us closer to working :nth-{,last-}child invalidation but not quite there.

My mistake, the invalidation test added in bug 1809659 fails, too (as well as the ones from bug 1809402).

:nth-child(An+B of <selector list>) and :nth-last-child(An+B of <selector list>) invalidation WPTs pass! Note that a @scope (:nth-child(An+B of <selector list>)) WPT exists and fails fails:
https://wpt.fyi/results/css/css-cascade/scope-invalidation.html
but that is expected since @scope has yet to be implemented (bug 1830512).
