I can reproduce this (you need to press "Add many strings" button), but I'm not sure we can control the placement of the items in the popup, i.e. this looks like something that GTK does if there (too?) many items in it.

It's an artifact of putting the current selection under the mouse cursor. I believe this is intentional GTK behavior. The list will scroll to fill the space if you select an item that is out of view.

Yes, this is the standard GTK behavior. We dealt with it in KiCad before: https://gitlab.com/kicad/code/kicad/-/issues/1866, and it looks like upstream GTK isn't going to change anything about this behavior: https://gitlab.gnome.org/GNOME/gtk/-/issues/270.

So it's not useful to keep this open as we have no way of ever fixing it. Thanks for the pointers Ian!
