All transitions are shown as history transitions

Model in Ptolemy:

Model in ptolemy browser:

All transitions are visualized as history transitions.
The original ptolemy model has only one history transition from A to D.
The model in the ptolemy browser shows both transitions as history transitions.
Moreover the initial state is on the right side.

Other transitions are also not always visualized correctly:
Ptolemy model with nondeterministic immediate transition from state to state2 and a preemptive history transition from state2 to state.

The same model in the ptolemy browser does not visualize immediate and preemption. This could be a result of the wrongly visualized history transition.
