ListBox with unfocusable child ListBoxRows breaks focus chain

Having a ListBox where can-focus is set to true for the ListBox itself, but false for the contained ListBoxRows, somehow breaks the focus chain.

What I am trying to accomplish is a ListBox which the user can focus and then alter the selection using the arrow keys. I.e. I only want TAB to move focus to the outer ListBox but not to each individual ListBoxRow.

Steps to reproduce / Current behavior

1. Run listbox-focus.c
2. Press TAB and observed that no widget gets focused
3. Press Shift+TAB three or more times and observe that the focus gets stuck at the top-most button

Expected outcome

When pressing TAB repeatedly, I expect the focus to move as follows:

1. ListBox
2. Button 1
3. Button 2
4. ListBox
5. ...

Observed on Fedora 35 running GTK 3.24.31.
