    GtkFontButton: Make sure the dialog isn't destroyed on delete-event
    
    The remaining code assumes that the dialog doesn't get destroyed, but
    it actually does on delete-event.
    
    In particular, the filter function and the preview text are lost as
    soon as the dialog is created and thus when we create a new dialog we
    don't have those properties to set on it anymore.
