Support AbortSignal.timeout

[johngeorgewright]

See https://developer.mozilla.org/en-US/docs/Web/API/AbortSignal/timeout

The static AbortSignal.timeout() method returns an AbortSignal that will automatically abort after a specified time.

Important thing, because it's feature breaks safari < 16

[elhardoum]

Here's a temporary fix:

// safari polyfill
if ("AbortSignal" in window) {
  AbortSignal.timeout = AbortSignal.timeout || ((duration) =>
  {
    const controller = new AbortController;
    setTimeout(() => controller.abort(), duration);
    return controller.signal;
  });
}

@elhardoum This cannot work because your setTimeout will start when AbortSignal.timeout() is called instead of the request itself. It also required a clearTimeout if the request finished earlier.

@mo @elhardoum Another static method AbortSignal.any() comes out:
