third_party/WebKit/LayoutTests/fast/events/onload-after-document-close-with-subresource.html

   1 <p>This test verifies that the load event doesn't fire until subresource content has loaded, even if you manually call document.close beforehand. See <a href="http://bugs.webkit.org/show_bug.cgi?id=13241">bug 13241</a>.</p>
