http://fetch.spec.whatwg.org/#cors-preflight-fetch-0 Add steps to set client and context? http://fetch.spec.whatwg.org/#concept-legacy-fetch http://fetch.spec.whatwg.org/#concept-legacy-potentially-cors-enabled-fetch Steps to set url, client and context are missing here too. But not worth updating this section anymore? Termination reason is not handled intentionally (only supposed to be used by XHR's functionalities and nothing would be introduced for Fetch API?)? The promise is rejected with a TypeError which seems inconsistent with XHR. Is this intentional?
