Breaking-change evidence from the source
This provides a very significant performance boost on pages with a huge number of DOM nodes, but there's a chance it could be a breaking change in very rare edge cases we haven't thought of. Please open an issue if anything related to shadows, rings, transforms, filters, or backdrop-filters seems to be behaving differently after upgrading.
