| <p>This test moves the iframe between two documents - once using this sequence:</p> |
| <pre> |
| document1.body.removeChild(iframe); |
| document2.body.appendChild(iframe); |
| |
| </pre> |
| <p>and then using 'adoptNode':</p> |
| <pre> |
| document2.adoptNode(iframe); |
| document2.body.appendChild(iframe); |
| |
| </pre> |
| <p>In the second case, the content of iframe should not be re-loaded and 'load' event should not be fired. Also, the timer started before reparenting should survive transition and fire.</p> |
| <p>Test also verifies that document.adoptNode() in case of not-rendered document (loaded by XMLHttpRequest) does not preserve the content of iframe.</p> |
| <p>Test succeeds if there are 'PASS' messages below and no 'FAIL' messages.</p> |
