Since commit 3fb02843, we no longer skip allocation for results that don't fit the width, and give them a 0x0 allocation instead. That has the unintended side effect of those children now being available to keynav. There are cases where we want 0-sized actors to be part of the focus chain (e.g. FocusTrap), but this isn't one of them, so explicitly exclude 0-sized children from keynav. https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/4470 Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1916>
