For editable comboboxes, the popup is placed below the combobox 
but for non-editable comboboxes, the popup is placed obscuring the selected 
item showing the list with the selected item  being highlighted
This can be seen in SystemPreference->Date&Time(for editable) and "Open 
Language&region"(for non-editable) so I think we should only fix it for 
editable one and not do anything for non-editable one..
