    <p>This tests that frame used when setting eventListeners on an EventTarget using addEventListener is
       the target nodes 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.</p>
