Browse Source 
This matches the prototype attributes.

Used by https://chatgpt.com/, where it runs this code:
```js
CSS.supports('animation-timeline: --works')
```
If this returns false, it will attempt to polyfill Animation Timeline
and override CSS.supports to support Animation Timeline properties.
