This is called when we create a new Document in LocalDOMWindow::createDocument.
This means that an iframe that points to a .swf would be using its parent's
origin to do the plugin data check rather than the top frame's origin. Is that
desired?

No, that's not desired. I changed it to get the main frame origin instead. ptal.
Thanks!
