    Description

      When ListModel is used with a WorkerScript, these signals are emitted after the actual changed:

      • QAbstractItemModel::rowsAboutToBeInserted()
      • QAbstractItemModel::rowsAboutToBeMoved()
      • QAbstractItemModel::rowsAboutToBeRemoved()

      They must be emitted before the change instead. QQmlListModelWorkerAgent must first call beginInsert/Move/RemoveRows(), then sync(), and finally call endInsert/Move/RemoveRows().
