GtkMenu’s own keynav code, which actually bothers to account for the layout of items, only happens if columns > 1. So, adding items to 1 column using a reverse loop meant they were placed in the Menu’s list of children in that order, and because we only have 1 column, Menu passes keynav up to MenuShell, which doesn’t adjust for the items’ positions. ‘Fix’ that here by adding items in the same order they’ll have when laid out in the Menu, so keynav does what you’d expect, not the opposite. For that, it’s simpler just to use gtk_container_add(). Let’s presume users are using add(), attach() with a non-inverted loop, or attach() with arguments that create 2+ columns and so GtkMenu keynav.
