[Kristof Zelechovski]

It seems the problem equally affects embedded objects can be loaded from a
different origin as well.

IMHO the basic problem here is allowing IFRAMEs to be cross-origin by
default. That causes many problems, some of which you know well, and others
you probably don't (e.g.
http://lists.w3.org/Archives/Public/www-svg/2008Sep/0112.html ). In fact, in
an ideal world, I think we'd default to same-origin restrictions on
everything --- IFRAMEs, images, scripts, etc --- and use a spec like Access
Controls to let sites opt-in to allowing their resources to be loaded from
specific other origins.
