*
* Ideally, that would be the end of the story, however due to complications
* dealing with document.domain, it's possible to end up in a scriptable
* helper with a wrapper, even though we should be treating the lookup as a
* transparent one.
*
* Note: So ObjectIsNativeWrapper(cx, obj) check usually means "through xray
* wrapper this part is not visible" while combined with
