> As for marking the tree with bits, I think we will still have to mark nodes as webvtt nodes. And presetting those bits may speed up things a little bit. (the only case when it's slower — when we don't have any cue styling rules at all).

I doubt there is significant performance difference. Walking the internal tree to mark time is not that fast either and is not very nice architecturally. I'm not sure if there is really need to mark WebVTT nodes at all, everything SelectorChecker sees after matching cue() is going to be WebVTT node (it could just be part of SelectorCheckingContext).

Yeah.
