Atom().Change fires always

var atom = Atom(Set("A", "B", "C"));

atom.Change += value => Console.WriteLine(string.Join(',', value)); 

atom.Swap(old => old.Add("D"));
atom.Swap(old => old.Add("E"));
atom.Swap(old => old);

A,B,C,D
A,B,C,D,E
A,B,C,D,E

Actually, I would like to use atom in the following context: var status = Atom(ConnectionStatus.Connected);

Now the problem is that the AtomChangedEvent<A> fires always, even if I provide swap(status, _ => ConnectionStatus.Connected).

I would like to have AtomChangedEvent<A> only when there is new value.
