Re: [whatwg/fetch] fetch() is unclear on which realm's Request it uses (#777)

@jakearchibald @wanderview and I discovered that implementations might not follow this for the `Request` constructor steps either, which typically say to use the "current settings object". Instead, if you do something like `frame.contentWindow.fetch(...)`, the service worker of `frame` ends up being used, rather than of the parent which did the invocation. So maybe most of these need to be changed to "relevant".
