Mac: QComboBox: The popup should be placed as such that the current item is over the combobox

QComboBox: On Mac the popup should be placed as such that the current item is over the combobox. However if the list is too long then it will not place it correctly. Attached is an example that shows this, if you choose items further down the list and pop it up then you will see the selected item is not where the combobox is currently placed.
