Re: [csswg-drafts] [scroll-animations-1] Rethinking timeline-phase (#7240)

Thanks for filing this! The timeline phase has added considerable complexity (and a somewhat confusing relation to animation phase) to the spec. In particular it needs to be involved in the animation phase calculations and properly held when we pause animations.

I agree that we can dramatically simplify the state logic in the spec by simply allowing time values to extend beyond the 0 to 100% range. As an additional consequence / feature, this would allow using a negative start / end delay to extend an animation beyond the normal range of a an intersection based timeline (e.g. ViewTimeline).

@birtles is there any reason having time values go outside of this range would be problematic?
