| +// notifications are already queued and just fire in the new page. |
| +// The bug, however, deals with XHR being still in progress in the browser process, |
| +// so when it is done and comes back with the routing_id of the closed window, |
| +// it has no way of finding the original iframe and firing onreadystatechange. |
| +// Having this timeout theoretically can make the test occasionally produce false |
| +// positive (if the reparenting takes longer then 1 second for example) however this |
| +// is very unlikely, and it won't make test flakey (false negative). |
