False alarm about breaking delegate binding

I have a c++ model object (`controller`) that has a QVariantList property (`stepList`) which contains a list of c++ objects which are owned by c++.

The steps are displayed using a repeater:

QtQuick.Repeater {
    model: controller.stepList

    QtQuick.Text { 
        required property var modelData // set by repeater 

        text: modelData.stepNumber
    }
}

When my component gets destroyed, the repeater and the controller get destroyed (and with the controller the steps are destroyed too).

When the step is destroyed, I get the following warning on my console:

Writing to "modelData" broke the binding to the underlying model

I believe this shouldn't be triggered from the repeater model getting destroyed.

For people experiencing this issue, I managed to come up with a reasonably simple workaround by resetting the model on destruction. This also needs that the repeater is destructed before the controller object.

QtQuick.Repeater {
    model: controller.stepList 

    QtQuick.Component.onDestruction: model=undefined

    QtQuick.Text {
        required property var modelData // set by repeater  
        text: modelData.stepNumber
    }
}
