requestAnimationFrame() polyfill does get applied for dedicated workers for no reason

### Expected behavior

a dedicated worker has full support for `requestAnimationFrame()`
https://developer.mozilla.org/en-US/docs/Web/API/DedicatedWorkerGlobalScope/requestAnimationFrame

```
/**
* Request animation polyfill
*/
export const requestAnimFrame = (function() {
if (typeof window === 'undefined') {
return function(callback) {
return callback();
};
}
return window.requestAnimationFrame;
}());
```

so this will get applied, which is not good.

what you want to check instead:
```
if (!globalThis.requestAnimationFrame) {
// smart polyfill
}
```
