What happened

Recently upgraded the platform to 2.1.3 and observed issues with TriggerDagRunOperator Operator. The child dag object when triggered from parent dag is not showing the start time in the tree view.
Also start time are showing up as null in dag_run table.

trigger_profile = TriggerDagRunOperator(
    task_id='trigger_profile', trigger_dag_id='child_dag'
)

What you expected to happen

ideally it should display timestamp.

How to reproduce

• create two DAGS.
• dag_main.py
• dag_child.py
• create an operator in dag_main.py

• trigger_dag_child = TriggerDagRunOperator(
    task_id='trigger_profile', trigger_dag_id='dag_child'
  

  )
• check start time in child dag
