You should not rely on that.  It is up to theme to pick either the
tree view or the menu mode.  This feature was really added for
platform styling/integration. Back when this was being designed, the
reasoning was that a picker popup looks like a menu on UNIX and like a
list on Windows, etc.

IMHO GtkComboBox has not been designed to handle thousands of items,
the UI is also not up to that. Given that you are going to need a
search feature is likely another indicator that the combo box UI will
not solve your problem.
