| This test checks to see if the DOM ContainerNode's NodeList cache is correctly invalidated when new content is parsed. | |
| If the test passes, you should see "before: not found", "after: found" and "onload: found". | |
| If the cache is not invalidated when the testElement is parsed, both before and after will be "not found", which is a failure. | |
| before: not found | |
| after: found | |
| onload: found |
