Re: [ServiceWorker] Returning a FetchPromise from fetch() (#625)

Ugh, I just realized that, pending some clever insight, the token approach doesn't work with combinators, unless you explicitly pass in the tokens as well, or have duplicate token combinators.


@NekR From what others have said, it appears preferable for a cancelled fetch (and cancelled things in general) to instead just be forever-pending; in real usage, rejecting just means that everybody puts a check at the top of their reject handler that does nothing if it was a cancel-rejection.
