When trying to create the following model in a "StateTransitionView" nested stated are displayed both on the state transition compartment and at the root of the diagram making hard to understand what happen.

 state s0 {
          state s1 {
            state s2;
          }
          state s3 {
              state s4;
          }
          transition t1 first s1.s2 then s3.s4;
    }
