Description
The ordering in the transition functions previous was that first the 'state' event was emitted (to the outside), secondly the class-internal on life-cycle function was called. At the cybus software, that turned out to be the root cause of some problem, because there may be events that should immediately be followed by other class-internal action, even before any outside event listener is notified about the state change. In the previous ordering that was impossible. By switching this to first call the class-internal life-cycle functions and then emit the event, it ensures that the class stays in ownership of its own state and its own state interpretation.
How has this been tested?
We changed this to fix some remaining bug in the cybus software in CYB-3488 (2022-03-07, appearing in release 1.0.78), and it has been in active use since then, so I would conclude that it works fine.
