You can see similar behaviour in the "Tree View -> List Store" example in
gtk-demo, gtk3-demo or gtk4-demo (from gtk2.0-examples, gtk-3-examples or
gtk-4-examples respectively). If you select an item low down the list,
then resize the window, you'll see that it's the top left corner that
stays fixed within the window, and the selected item doesn't necessarily
stay visible.
