[Matthias Clasen <matthiasc src gnome org>]

commit 4bdd94fd3ffa07a05691d4028d227bec2484f7c4

    gtk-demo: Simplify the tagged entry demo
    
    No need for an intermediate box widget here;
    we can just use a box layout. As a side-effect,
    this fixes the theme to apply to the selection.
    
    Fixes: #3005
