| Test that the second argument of window.postMessage is ignored if it is not a message port. You should see messages '1' through '6', followed by 'done', received below. | |
| Note that the HTML5 spec implies that an exception should be raised instead, so this test will need updating once that new behavior is implemented. | |
| Received message '1' | |
| Received message '2' | |
| Received message '3' | |
| Received message '4' | |
| Received message '5' | |
| Received message '6' | |
