> * Consider ScrollTimeline with scroll range 100% to be _terminal finite_. (I am sure there are probably better terms for this but I am just using this to just mean that it is not possible to go beyond their last time value).
> * When [setting timeline of an animation](https://drafts.csswg.org/web-animations/#setting-the-timeline), if that timeline is _terminal finite_, then consider that animation to be _prefers fill-forward_.
> * When [setting the associate effect](https://drafts.csswg.org/web-animations/#setting-the-associated-effect), if the animation is a _prefers fill-forward_ and the effect's fill mode was not explicitly specified (we may need to introduce 'fill: auto' as a default value), then set the effect's fill to be forward.

I might not be following correctly but this sounds to be pretty stative? As it, it depends on the order in which these operations are performed? I think it shouldn't matter whether you associate the timeline or the effect first (and I don't think you want to magically update the fill mode -- but rather keep it as `auto` but define what that means in this situation, i.e. only update the computed fill mode).
