Making a subscription change which does not actually change the set of in-view objects can result in the server sending us a DOWNLOAD message with estimate=0 followed by one with estimate=1. Depending on the previous state of notifications sent, this may result in sending a notification for estimate=0 but not the estimate=1 notification.
