Hi. @bbovenzi , @potiuk I looked at the code in the commit and it seems to me that the "root" part of the link is omitted in the url_root.

Old one:
url_root = url_for(
"Airflow.graph", dag_id=dag_id, root=task_id, execution_date=execution_date.isoformat()
)

New one:
url_root = url_for(
"Airflow.grid",
dag_id=dag_id,
task_id=task_id,
dag_run_id=run_id,
tab="graph",
map_index=attr.get("map_index", -1),
)

There is no root in the new one. I think, the "root" filtering (very helpful in large Dags) should remain, only "task_id" should be added.
