    main: Quick hotfix to workaround gtk #4880
    
    - For Save As dialog, stop focus from being stolen from the filename
      entry and over to the search box. Hopefully this bug will be fixed in
      GTK soon and this workaround can be removed.
    - See: https://gitlab.gnome.org/GNOME/gtk/-/issues/4880
