   IMO this should be expected. The `end` task is expecting an input from the `task_to_fail` output but the latter task has failed and doesn't produce an `XComArg`. The `end` task does _actually_ run so the trigger rule is respected, but fails with:
   ```bash
   airflow.exceptions.AirflowException: XComArg result from task_to_fail at taskflow_trigger with key="return_value" is not found!
   ```
   
   What would you expect the behavior to be in this scenario?
