  Log Message:
  -----------
  postMessage from RemoteFrame should have correct event.source
https://bugs.webkit.org/show_bug.cgi?id=265543
rdar://118946789

Reviewed by Pascoe.

event.source should be the DOMWindow of the frame that sent the message,
even if it is a RemoteDOMWindow.  It shouldn't be the DOMWindow of the
frame that is receiving the message.
