### Apache Airflow version
3.0.4
### If "Other Airflow 2 version" selected, which one?
_No response_
### What happened?
I've migrated to airflow 3.0.4 version.
I'm used to passing attributes through xcoms between runs but it's returning
None all the time now.
It works pulling from other tasks, I works for same task if I push Xcom just
before pulling it, but not for previous runs.
Researching it, I've discovered that I was using old Xcom backend path, but
changing it
( airflow.sdk.execution_time.xcom.BaseXCom >>
airflow.sdk.bases.xcom.BaseXCom )
didn't solve the issue.
The code I use is just:
@task
def tst_xcom(**context):
ti = context['ti']
xcom = ti.xcom_pull(task_ids='tst_xcom', key='ll')
logger.info(f'prev_xcom: {xcom}')
import pendulum
ti.xcom_push(key='ll', value=f'll_{str(pendulum.now())}')
Xcom can be seen in Xcom tab after each run, Xcom exists in db, but still
pull wont work.
Checked that on Airflow 3.0.3 as well - same.
Thank you in advance!
### What you think should happen instead?

### How to reproduce
Airflow 3.0.4 / 3.0.3, task pulling itself's previous xcom.
