Unfortunately, I cannot extract the sample for now. But found solution myself:
In position_func count preferred height of all GtkMenuItems in menu and run gtk_widget_set_size_request() with resulted height. Then menu will expanded to unscrollable menu, if possible. Inserting item to visible menu result hiding it, then this hack will works.

gtk_widget_queue_resize() may not work because GtkMenu requires
some additional actions, see its static function menu_queue_resize().
But gtk_menu_shell_insert() and similar functions call it correctly
and should be sufficient.
Can you wait for the response from DBus and populate the menu
before it is displayed?
Can you provide the sample code?
