<h1>Description</h1>
<p>This test validates window.performance.timing 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.timing are correct and
the frame below ends with a green background.</p>
