ListView should emit currentIndexChanged -1 on setting empty model

Had ListView with QList<QObject*> model. Let say user ask to delete currently selected object. Apps delete object, update model and set currentIndex to -1. Everything alright, onCurrentIndexChanged is printing info about setting currentIndex to -1:

onCurrentIndexChanged: console.log("currentIndex" + currentIndex)

But if the object was the last object and updated model is become empty, Qt automatically set currentIndex of ListView to -1 without emitting CurrentIndexChanged. And setting currentIndex -1 in app does nothing, because it is already -1!
So all bindings with currentIndex will not be updated in this case:

enabled: idList.currentIndex >= 0

I suppose that ListView should emit currentIndexChanged -1 in this case.

For now in places where currentIndex is needed a workaround is to check with currentIndex also model.length.

enabled: ((idList.model.length > 0) && (idList.currentIndex >= 0))
