<h1>Description</h1>
<p>This test validates the value of window.performance.getEntriesByType("navigation")[0].(type/unloadEventEnd/unloadEventStart) with a reloaded navigation.</p>
<p>This page should be loaded with a green background frame below. The frame will be automatically reloaded
and then verified that
<ul>
<li>The window.performance.getEntriesByType("navigation").unloadEventStart > 0 after reload</li>
<li>The window.performance.getEntriesByType("navigation").unloadEventEnd > 0 after reload</li>
</ul>
