<h1>Description</h1>
<p>This test validates the ordering of the window.performance.timing attributes.</p>
<p>This page should be loaded with a yellow background frame below which contains an unload event
handler.</p>
<p>After the page loads, the frame is navigated to a new blank page with a green background. At this point, the navigation timeline is verified</p>
<p>This test passes if all of the checks to the frame.window.performance.timing attributes are
correct throughout the navigation scenario and the frame below ends with a green background.
Otherwise, this test fails.</p>
<h1>Setup</h1>
<div id="log"></div>
<br />
<iframe id="frameContext"
onload="/* Need to make sure we don't examine loadEventEnd
until after the load event has finished firing */
setTimeout(onload_test, 0);"
src="resources/blank_page_unload.html"
style="width: 250px; height: 250px;"></iframe>
