But see:
where I disagree with this "snapshot" bit and:
where Øyvind Stenhaug replies on the other side.

The biggest reason that I don't like the snapshot idea is that
exposes which changes are considered simultaneous, which is a
concept I'd rather expose as little as possible since making the Web
depend on it reduces future opportunities for optimization.
Honoring dynamic changes means we'll reliably honor changes that are
made right after the change that starts the animation.
