    list-base: Show the single click cursor when in single click mode
    
    We used to do this in gtk3, but it appears to have been lost in the
    switch.  In gtk3 we had to check the hover state and change the
    cursor on the fly.  In gtk4 there's a convenient
    gtk_widget_set_cursor_from_name() function.
