ComboBox keypress discrepancy

[Dirk Lemmermann]

Regarding expected behaviour: in native combo boxes / dropdowns on Mac the TAB key is doing nothing when the popup is open. If you want to select an item you need to use the arrow keys. So I guess that is what I would expect for navigating the element. But that does not mean that the key event can’t fire, right? Some subclass / custom control might have a need for it.
