In case of isolated tree mode the children changed notification happens after the deferred cache update like in non-isolated tree mode, but then it's deferred again by the notification post timer. This affects layout tests doing things like foo.appendChild(bar) + foo.childAtIndex(0), because in isolated tree mode foo.childAtIndex(0) returns null, the child wrapper hasn't been attached yet with the ax isolated object.
