[whatwg] Foreign fallback appcache entries

"Foreign" means that the main resource has a different manifest than the one referencing it. E.g.


<html manifest="bar.manifest">

So, I don't think that the same origin requirement answers this. WebKit bug <https://bugs.webkit.org/show_bug.cgi?id=44406> has a live demo (Firefox 3.6.10 handles it correctly, according to my reading of the spec).
