What happened?

After upgrading to Airflow 2.8.0, I've found out that the Details tab is empty for mapped tasks

What you think should happen instead?

Details tab should appear, just like before

How to reproduce

1. Run the following DAG

  with DAG(
      dag_id="test_mapped_tasks_ui",
      schedule=None,
      catchup=False,
      max_active_runs=1,
      render_template_as_native_obj=True,
  ) as dag:
  
      @task
      def my_task(idx: int) -> None:
          print(f"Task {idx} done")
  
      my_task.expand(idx=list(range(1, 10)))

2. Open the Details tab of my_task

Likely should be address before 2.8.1 (cc: @bbovenzi @pierrejeambrun).

@csp33 -> can you see any errors in console log (open inspect view in your browser) when you open the details tab? Could you please post it here?
