[css-houdini-drafts] [css-animation-worklet] IDL for StatelessAnimator doesn't make sense (#906)

bzbarsky has just created a new issue for https://github.com/w3c/css-houdini-drafts:

== [css-animation-worklet] IDL for StatelessAnimator doesn't make sense ==
I was reading through https://drafts.css-houdini.org/css-animationworklet-1/ and the IDL global/exposure bits don't make any sense to me.  For example, the draft has:
```
[Exposed=AnimationWorklet, Global=AnimationWorklet, Constructor
 (optional any options
)]
interface StatelessAnimator {
};
```
This defines an object which is supposed to be a global (hence `Global=AnimationWorklet`) but has a `Constructor`, so you can create multiple of them in a given global?

The IDL spec explicitly says for `[Global]`:

> The [Global] extended attribute must not be used on an interface that can have more than one object implementing it in the same Realm.

which means it's not really compatible with `[Constructor]`.  I filed https://github.com/heycam/webidl/issues/744 to make that very explicit.

Anyway, is this object constructible or a global?  It can't really be both.
