    selection-toolbar: Use the PhotosApplication to retrieve the toplevel
    
    No functional change. This is what gnome-documents does so lets do the
    same thing.
    
    Also, Mutter is not attaching the modal for some reason. Doing the
    exact same thing as gnome-documents would help debug this later.
