I agree with Tab. It seems like your editor is trying to impose a timeline
structure on something that doesn't have one. If your tool is all-encompassing
(meaning that the author uses it to control what JS runs when, and therefore
when the "dynamic" style gets applied), then the problem goes away because
you know when the animation is going to run.

If you replace animation-* with some other property with a shorthand, like border-*,
why is the problem different?
