A11Y: Gtk Combobox is inaccessible
The current implementation for Gtk Comboboxes does not expose the items to Atspi2, because it uses the same infrastructure as the treeview, so it has the same problem as described in #4274. Does the combobox a replacement suggested as well, or will we be required to implement the creation of an accessibility object for each renderer? And if yes, what would be the best place to see a place where such object is created from scratch, e. g. is the implementation in GtkWidget the simplest, or is there a better place to see an implementation of a GtkAccessible?
