Forbidden transition resets visualization to initial state

[davidlav]

The machine below requires moving through states stepOne and stepTwo, in addition to requiring an approval. The approved context property ought to be able to be set at any state (i.e. start, stepOne, stepTwo, or awaitingApproval) as it is independent of what "stage" you're at. It is, however, a necessary condition for reaching success.

This implementation (credit to @semopz) shows the machine acting properly as described above:

However, clicking APPROVAL_GIVEN while in the states stepOne, stepTwo, or awaitingApproval in the Visualizer (below) will erroneously reset the state to start.
