| <p>This test validates that the window.performance.timing attributes change when a page is reloaded.</p> |
| |
| <p>This page should be loaded with a green background frame below. The frame will be automatically reloaded |
| and then verified that the window.performance.timing attributes have been updated to the new reloaded navigation timings.</p> |
