Combobox does not scroll to selected item

The Qt Controls 2 ComboBox component does not scroll down to the selected index when not all items can be displayed on the screen at the same time.

Steps to reproduce:
1.) Add as many elements to a ComboBox model so that they do not fit on the screen (the combo box has to be scrolled down).
2.) Scroll down the combo box, select an item, and close the combo box.
3.) Open the combo box again. The combo box does not scroll down to the selected item.
