| <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> |
