CONSOLE MESSAGE: Blocked a frame with origin "http://127.0.0.1:8000" from accessing a frame with origin "http://localhost:8000". Protocols, domains, and ports must match.
This tests that frame used when setting eventListeners on the window with the shortcut (onclick, etc), is the window's frame. (rdar://problem/5426142). This test passes if you don't see an alert dialog with the domain of "localhost" in it and an "Unsafe JavaScript" warning is logged to the console.
