Root State Machine terminates when Sub-Container returns Outcome named "Preempted"

[tropappar]

Setup:
I have a state machine that contains a concurrency container. This container has an outcome called preempted. The root state machine does not contain such an outcome.

Error:
Once the concurrency container reaches the outcome preempted, the whole state machine terminates, even though it should transition to another state.

This is the terminal output:

Behavior execution finished with result preempted.

"preempted" is a key word in FlexBE's handling of "PreemptableState" and "PreemptableStateMachine". Don't use. Suggest "canceled" instead
