::scroll-marker click detection has been requested by our partners trying out CSS Carousels ::backdrop can be used to avoid intersection checks on dialog dismiss (by just inspecting event.pseudoTarget) ::view-transition can be used for mid-flight interception and starting of new animations based on the coords of ::view-transition-old (from bramus@) some other ideas/future extensions - https://github.com/danielsakhapov/CSSPseudoElementDoc
