A little more detail, as discussed in #webkit:

- If animation-play-state is to be left after all, it just needs to be
implemented on the desktop, then the first part is resolved.

- The scrubbing hooks need a little care to account for the fact that a given
element may have many animations applied to it. For a given (element,
animation-name) tuple, I want to be able to get and set progress percentage or
time. Time is a little interesting: while it makes intuitive sense (at least as
relates to the percentage) for time to be relative to the animation's
beginning, it might make sense to provide a variant which works in *global
time*, which would count the animation-delay property time. That way, a
scrubber moving from 0 to 10 seconds could pass the same value for all
animations and get the expected results, without having to consider each
animation's delay.
