Re: [csswg-drafts] [web-animations-1] Play state of an animation with an unresolved timeline (#5400)

I'm not sure I quite follow this part. I _think_ it actually makes sense to me that the animation is finished/running at this point?

Is there precedent for distinguishing between the lack of an associated timeline and an associated but inactive timeline? I thought we always treated those two as the same? (i.e. the lack of an associated timeline can be thought of as being associated with a "null timeline" that is always inactive).

> If the timeline is explicitly set to null, should the play state be allowed to be in a running state?

I _think_ so?
