[AIRFLOW-3060] DAG context manager fails to exit properly in certain circumstances
> DAG context manager fails to exit properly in certain circumstances

> Key: AIRFLOW-3060
> URL: https://issues.apache.org/jira/browse/AIRFLOW-3060
> Project: Apache Airflow
> Issue Type: Bug
> Components: DAG
> Reporter: Newton Le
> Assignee: Newton Le
> Priority: Major
> Fix For: 2.0.0

>
> In certain circumstances, such as in more complex DAGs where users utilize helper functions to add tasks, it may be possible to get into a condition where effectively there is a nested DAG context using the same DAG. When this happens, exiting both contexts does not reset `_CONTEXT_MANAGER_DAG`.
> This is especially problematic because the problem is seen in a later DAG, and the source of the error is not apparent.
