Probably it's a consequence of this work for porting GtkMenuBar to use css gadgets internally: https://gitlab.gnome.org/GNOME/gtk/commit/700286c6
You should be able to get the appropriate size if you add menu items to the bar, i.e. as long as the menubar is not empty you get the appropriate height with gtk_widget_get_allocated_height().
