    Description

      When the QAbstractItemModelReplicaImplementation receives the reply of the data fetch request the data are assigned to the model rows that were valid at the the time the request was sent. If rows have been moved in the meantime this assignment is not correct.

      Instead the replica must track all requested rows via QPersistentModelIndexes.
