Error with QObject model data in subclass of subclass of QAbstractListModel

I'm trying to write a more generic subclass of QAbstractListModel which only needs the roles and the data as a list.

This works fine if I'm using dict as model data. But using a QObject as model data somehow breaks QML.

Please see the attached example. It fails with the error:

QQmlExpression: Expression file:///...bug.qml:17:23 depends on non-NOTIFYable properties:
QQmlDMObjectData::name

The exact same code without an additional subclass (`ConcreteModelWorking`) works.
