parent (origin P, P != O)
child (origin O, same as grandparent)
then the grandparent and the child are in the same UoRSOBC. The grandparent
can say `frame.contentWindow.frames[0]` to get its grandchild
frame.contentWindow should return null in this case.
But the grandparent can do window[0][0] (aka window.frames[0].frames[0])
to get the grandchild.
