Attached 'model' property in the TableView delegate points to the model object instead of model item's data

In the TableView delegate model data points to the model object, but should point to the model element data for models like ListModel. Though, modelData points to the model element data for models like JavaScript Array.
Executing attached program results in following output:

JS Array	model: [[object Object]] modelData: [object Object]
ListModel	model: QQmlListModel(0xf80350) modelData: test
