| // 1. Open a new window and navigate to a test URL. |
| // 2. Navigate the window to a second page. |
| // 3. Trigger the clear-site-data header either by window.open() or loading an |
| // iframe from the second page. |
| // 4. Navigate back to the first page. |
| // 5. Assert that the first page is or is not cached. |
