phi-friday opened a new issue, #39863:
URL: https://github.com/apache/airflow/issues/39863
### Apache Airflow version
2.9.1
### If "Other Airflow 2 version" selected, which one?
_No response_
### What happened?
When I modified the dataset during runtime, as shown below,
```python
outlets: list[Dataset] = context["outlets"] # pyright:
ignore[reportTypedDictNotRequiredAccess]
outlets[0].extra = (outlets[0].extra or {}) | {"test_value": 123}
```
In XCOM, I can see these changed values.

However, it will look different in detail.

And if I check the triggered DAG, extra is passed unchanged.

### What you think should happen instead?
It has to be one or the other.
### How to reproduce
```python
from __future__ import annotations
from datetime import UTC, datetime
from airflow.datasets import Dataset
from airflow.decorators import dag, task
dataset = Dataset(uri="dataset_example")
@dag(
dag_id="append_test",
start_date=datetime(2023, 11, 1, tzinfo=UTC),
schedule=None,
default_args={"do_xcom_push": False},
catchup=False,
max_active_runs=1,
tags=["dataset", "example"],
)
def dataset_trigger_example() -> None: # noqa: D103
@task.python(outlets=[dataset])
def setup_dataset() -> None:
from airflow.operators.python import get_current_context
context = get_current_context()
outlets: list[Dataset] = context["outlets"] # pyright:
ignore[reportTypedDictNotRequiredAccess]
outlets[0].extra = (outlets[0].extra or {}) | {"test_value": 123}
_ = setup_dataset()
@dag(
dag_id="append_test_comsumer",
start_date=datetime(2023, 11, 1, tzinfo=UTC),
schedule=[dataset],
default_args={"do_xcom_push": False},
catchup=False,

tags=["dataset", "example"],
)
def dataset_consumer_example() -> None: # noqa: D103
@task.python()
def echo_in_python() -> None:
from pprint import pprint
from airflow.operators.python import get_current_context
context = get_current_context()
pprint(context.get("triggering_dataset_events")) # noqa: T203
_ = echo_in_python()
dataset_trigger_example()

```
