We should extend the syntax of keyframe selector to: `<keyframe-selector> = from | to | <percentage [0,100]> | <timeline-range-name> <percentage>` This includes a new syntax, `<timeline-range-name>`, which is defined only for [view timeline](https://drafts.csswg.org/scroll-animations-1/#view-timelines-ranges) now. for other cases, we ignore this keyframe selector: > Keyframes are attached to the specified point in the timeline. If the timeline does not have a corresponding named timeline range, then any keyframes attached to points on that named timeline range are ignored.
