Ehsan Akhgari 01d300654e Bug 1179567 - Make ServiceWorker keep its document and window alive; r=baku
Without this, ServiceWorker::PostMessage won't work when the window has
been cleaned up, since at that time the event targets are disconnected
from their owners and GetParentObject() will return null.
