Re: [whatwg/fetch] Fix: Appending a header to headers with "request-no-cors" guard (#840)

So I think this should use https://fetch.spec.whatwg.org/#concept-header-list-get rather than "combined value" and then we need to branch on null. If the existing value happens to be the empty string, we should still append ", " and the given value to it.
