Why? CrossOriginPropertyFallback returns undefined for @@toStringTag (see https://html.spec.whatwg.org/multipage/browsers.html#crossoriginpropertyfallback-(-p-)).

It seems like our implementation doesn't follow that behaviour. For cross-origin windows in Gecko, we report "[object Window]".

e.g: data:text/html,<iframe id=i src=http://example.com></iframe><script>document.body.innerHTML += i.contentWindow;</script>

On both Firefox and Chromium this prints out [object Window] not [object Object] like it would according to the spec.

ni? :annevk for clarification on this oddity.

That's not a proxy for a cross-origin object. You need to wait for onload. (You're looking at about:blank.)

Testing shows that we are doing the right thing (and so do Chrome and Safari TP says annevk).
