| 69 <p>This test validates window.performance.timing remains constant when a |
| 70 document is replaced using document.open.</p> |
| 71 |
| 72 <p>This page should be loaded with a yellow frame below. It then replaces the |
| 73 document in that frame with a green document.</p> |
| 74 |
| 75 <p>The test passes if all of the checks to performance.timing are correct and |
| 76 the frame below ends with a green background.</p> |
