@graouts How does the `ready` promise get resolved without an active timeline?
The second condition for [resolving the ready promise](https://drafts.csswg.org/web-animations-1/#ready) is:
> - the animation is associated with a [timeline](https://drafts.csswg.org/web-animations-1/#timeline) that is not [inactive](https://drafts.csswg.org/web-animations-1/#inactive-timeline).
If I do:
```js
const anim = new Animation(new KeyframeEffect(document.body, { opacity: [0, 1] }, 1000), null);
anim.play();
requestAnimationFrame(() => {
console.log(anim.pending);
});
```
The animation (and it's `ready` promise) should still be pending because there's no active timeline to resolve the start time against.
