PathView currentIndex not maintained when changing model

I have setup an example with 3 columns. The 1st and 3rd columns are PathView, while the 2nd one is ListView. All 3 columns have currentIndex set to 2 at startup. When I click the 'Set Model' button, the model of both 2nd and 3rd column are changed to defaultModel. The currentIndex of ListView (2nd column) remains at 2. However, the currentIndex of PathView (3rd column) is something else. I would expect the PathView to keep the currentIndex unchanged even if I change it's model.
