	* gtk/gtkcombobox.c (gtk_combo_box_set_active): Move the actual
	implementation into a new gtk_combo_box_set_active_internal()
	function, which doesn't do the short-circuiting.
	* gtk/gtkcombobox.c (gtk_combo_box_model_row_deleted): Use
	set_active_internal() here, since the active item may change here,
	although the index is unchanged.

	* gtk/gtkcombobox.c (gtk_combo_box_menu_position): Reintroduce the
	traditional option menu placement of the popup for regular combo
	boxes. Grids and editable combo boxes use the combo-like placement
	below the entry.  (#136021)
	* gtk/gtkcombobox.c (gtk_combo_box_menu_button_press):
	* gtk/gtkcombobox.c (gtk_combo_box_popup): Call gtk_menu_set_active()
	before popping up the menu, to make the placement work.
