> When I run an airflow backfill using the airflow cli (i.e. airflow backfill -s somedate -e someotherdate dag_id), if the start date of the backfill is before the start_date of the dag, then airflow ignores depends_on_past and runs tasks in parallel for different days that have depends_on_past set to true. If the end date of the backfill is after the start_date of the dag then the backfill will begin respecting depends_on_past once it reaches the start_date of the dag. Seems like a bug.
