Description Chris Dumez 2022-05-25 10:38:49 PDT

Move some of the work from Element::insertedIntoAncestor() / removedFromAncestor() to subclasses. These functions are hot and should be kept as efficient as possible. There is no reason for every Element to pay run-time cost for checks that only apply to article or label elements.
