      """Test state loops:
  
      - executing -> cancelled -> resumed(fetch)
      - executing -> long-running -> cancelled -> resumed(fetch)
  
      The task execution later terminates with a failure.
      This is an edge case interaction involving task cancellation and a task that does not
      deterministically succeed or fail when run multiple times or on different workers.
  
      Test that the task is fetched from the other worker. This is to avoid having to deal
      with cancelling the dependent, which would require interaction with the scheduler
      and increase the complexity of the use case.
