### Apache Airflow version main (development) ### If "Other Airflow 2 version" selected, which one? _No response_ ### What happened? https://airflow.apache.org/docs/apache-airflow/stable/authoring-and-scheduling/deferring.html#exiting-deferred-task-from-triggers On tasks with retry when a `TaskFailedEvent` is from trigger the task is marked as failed with the retries not executed for the failed tasks. Similar issue with callbacks and also email_on_failure, email_on_retry also not being honored. This happens in main and also 2.10.4 . PR related https://github.com/apache/airflow/pull/40084 ### What you think should happen instead? Retries, callbacks and emails on failure should be honored. ### How to reproduce 1. Create following triggers and dag with retries and callback. 2. Run the dag with `TaskFailedEvent` emitted from the trigger. 3. The dag is marked as failed without retries and callbacks executed. 4. Uncomment yielding `TriggerEvent` and run the dag again with new code. 5. Retry happens and the failure callback is also executed. ```python # plugins/custom_trigger.py from __future__ import annotations import asyncio import logging from airflow.triggers.base import BaseTrigger, TriggerEvent, TaskSuccessEvent, TaskFailedEvent from airflow.utils import timezone class StateTrigger(BaseTrigger): def __init__(self, state): super().__init__() self.state = state def serialize(self): return ("custom_trigger.StateTrigger", {"state": self.state}) async def run(self): if self.state == "success": yield TaskSuccessEvent() else: yield TaskFailedEvent() # yield TriggerEvent(self.state) ``` ```python # dag_state_test.py from __future__ import annotations from datetime import datetime from custom_trigger import StateTrigger from airflow import DAG from airflow.models.baseoperator import BaseOperator class MultipleDeferTrigger(BaseOperator): """Multiple defer trigger.""" def __init__(self…
