That would work altough I think it's a bit hacky as when I listen on the
`selectionModelProperty` I still would get the noop selection model.
I'm in general not a fan of 'self-changing' properties. When a null value is
possible, guards against are needed.
Unfortunately there is no built-in way to forbid null in Java as whole.

But then I don't see any advantage as it makes no difference if we check for
NONE model or null. Checks are needed in any case.
