Details

Gecko seems to treat the document inside of <object> as a top level document with no parent.
So the object.contentWindow.location.ancestorOrigins return [] in Firefox.

While <object> has a container document, so its ancestorOrigins must be [window.origin].

Step 3 of internal ancestor origin objects list creation steps is violated.

NI myself on this

FWIW, we have a test for this.
