To reproduce:
1. Open 'Simpler AnyState Interrupt Bug' project
2. Play the scene.
3. Select the gameobject and open the Animator window
4. Set Reset true to trigger the Any State transition.

Expected vs Actual: Any State transition does not get interrupted even though the conditions for the State1 to State2 transition are set and the Interruption Source is set to include the next state.

6. Set Reset true to trigger the Any State transition.
7. While the Any State transition is occurring set Reset true again.

Expected vs Actual: Any State transition does not interrupt itself to trigger another Any State to State1 transition event though it's conditions are set and the Interruption Source is set to include both the next and current states.
