<h1>Description</h1>
<p>This test validates window.performance.getEntriesByType("navigation") remains constant when a
document is replaced using document.open.</p>
<p>This page should be loaded with a yellow frame below. It then replaces the
document in that frame with a green document.</p>
<p>The test passes if all of the checks to performance.getEntriesByType("navigation") are correct and
the frame below ends with a green background.</p>
<iframe id="frameContext" onload="onload_test();" src="resources/blank_page_yellow.html" style="width: 250px; height: 250px;"></iframe>
