   Reproduce the scenario described in this issue with a python operator which causes failed task at 50% chance
   
   ```
   @task(task_id=f"sleep_and_randomly_fail", retries=1)
   def my_sleeping_function():
       time.sleep(5)
       if random.uniform(0, 1) > 0.5:
           raise ValueError("Mock Exception.")
   ```
   
   From the DAG run results it seems to me this issue is already addressed, as in the following snapshot we can see both failed 1st run and successful 2nd run in gantt chart. Under the hood, reruns of a tasks are stored as different task instances.
