[Bug 22346] Security: Check origins when invoking a method, getter, or setter on an object using the property descriptor of another

https://www.w3.org/Bugs/Public/show_bug.cgi?id=22346

--- Comment #18 from Anne <annevk@annevk.nl> ---
I'm not sure what the right behavior is. I wish I was a little more confident,
but I'm mostly still struggling with the material here.

For crossOriginProperties it seems problematic since the active document
changes which means that certain named properties need to change too ("the
browsing context name of any child browsing context of the active document
whose name is not the empty string"). Not sure about the map.

Would it be better to store this on Document, along with all the other "global"
state we store there?
