| <p>This test checks that resource ids are unique across pages by opening |
| two pages that both contain an iframe that loads the same number of |
| resources, then adopting the iframe from one page to the other. If resource |
| ids are not unique across pages, these pages will have the same resource ids |
| and the adoptNode will fail due to an id collision. The iframe is then |
| adopted back into its original page to check for id collision from failure |
| to properly remove its resource id from the original page. </p> |
