12<p>This test verifies that document.writing into a newly-opened empty
13window does not cause crashes or assertion failures, even if it
14triggers subresource loads. If you have popup blocking enabled you can
15click the button below to test. The test only works in Safari, because
16it depends on behavior with resource identifiers, which are provided
17by the app.</p>
