```
### What you think should happen instead?
The signature should not expire for when the task is still running.
### How to reproduce
I have set my AIRFLOW__API_AUTH__JWT_EXPIRATION_TIME along with
session_lifetime_minutes to "43200" or 12 hours to control the sign out of
logged in users after this time. Also i am explicitly setting a
apiSecretKeySecretName and jwtSecretName with appropriate k8 secrets.
This does not happen for all dag runs but when scheduling multiple dag runs
with multiple tasks. Also the dag fails long before 12 hours set for the jwt
expiration time.
