Implements idea described in https://docs.google.com/document/d/1vEW86DaeVs4uQzNFI5R-_xS9TcS1Cs_EUsHRSgCHGu8 Invalidation sets are used to reduce the number of elements marked for style recalculation by collecting metadata from style rules about the dependencies between properties that could affect an element’s style. Currently, this optimization is only applied to style invalidation triggered by class list mutations on an element.
