timeout on Dynamic Task mapping : skipped inner task , task status is still success

### Apache Airflow version 2.8.1 ### If "Other Airflow 2 version" selected, which one? _No response_ ### What happened?  this is confusing and not obvious to find the problem when just looking at the grid view on a complex dag ### What you think should happen instead? maybe we should mark the task as skipped or failed ### How to reproduce ```python from datetime import timedelta from airflow.operators.python import PythonOperator from pendulum import today from airflow import DAG dag = DAG( dag_id="test_dag", schedule_interval=None, dagrun_timeout=timedelta(seconds=5), start_date=today("UTC").add(days=-1) ) with dag: def something(arg): import time time.sleep(int(arg)) PythonOperator.partial( task_id="toto", python_callable=something, ).expand(op_args=[("10",), ("5",), ("4",)]) ``` ### Operating System ubuntu 22.04 ### Versions of Apache Airflow Providers _No response_ ### Deployment Docker-Compose ### Deployment details _No response_ ### Anything else? _No response_ ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md)
