FetchObserver (for a single fetch) #607
Description
In #447 (comment) @jakearchibald sketched some APIs based on @stuartpb's work which @bakulf then implemented:
https://developer.mozilla.org/en-US/docs/Web/API/FetchObserver- https://dxr.mozilla.org/mozilla-central/source/dom/webidl/FetchObserver.webidl
- https://dxr.mozilla.org/mozilla-central/source/dom/webidl/Request.webidl#59
That issue got closed after we landed a subset of that API in Fetch (you can finally abort a fetch). Let's discuss the remainder here (though not priorities, that's #436).
