…o bet set via `animation-timeline` While most `animation-*` CSS properties should _not_ have an effect once a `CSSAnimation` object has had its `effect` property set via the bindings, the `animation-timeline`, like the `animation-play-state` and `animation-name` properties, should not follow that pattern since it is relevant to the _animation_ and not the animation _effect_. The relevant WPT test is updated in web-platform-tests/wpt#51057.
