ComboBox: selecting items with children, Gtk2 vs Gtk3
Steps to reproduce
Compile the sample code combo.c, it builds a tree model with an item that has child items, and uses that model in a ComboBox.
Expected outcome (Gtk2)
Current behavior (Gtk3)
So how does one select "Item with children", using the mouse, under Gtk3? The item can be selected using the keyboard, but apparently not with the mouse. Is there a way to get the Gtk2 behaviour back with Gtk3?
I tested this with Gtk2 2.24.31 and Gtk3 3.22.26.
