### Apache Airflow version 2.3.0 (latest released) ### What happened While testing the [example](https://airflow.apache.org/docs/apache-airflow/2.3.0/concepts/dynamic-task-mapping.html#mapping-over-multiple-parameters) given for `Mapping over multiple parameters` I noticed only 5 tasks are being mapped rather than the expected 6. The doc mentions: ``` # This results in the add function being called with # add(x=2, y=5) # add(x=2, y=10) # add(x=4, y=5) # add(x=4, y=10) # add(x=8, y=5) # add(x=8, y=10) ``` But when I create a DAG with the example, only 5 tasks are mapped instead of 6:  ### What you think should happen instead A task should be mapped for all 6 possible outcomes, rather than only 5 ### How to reproduce Create a DAG using the example provided [here](Mapping over multiple parameters) and check the number of mapped instances:  ### Operating System macOS 11.5.2 ### Versions of Apache Airflow Providers apache-airflow-providers-amazon==3.3.0 apache-airflow-providers-celery==2.1.4 apache-airflow-providers-cncf-kubernetes==4.0.1 apache-airflow-providers-databricks==2.6.0 apache-airflow-providers-elasticsearch==3.0.3 apache-airflow-providers-ftp==2.1.2 apache-airflow-providers-google==6.8.0 apache-airflow-providers-http==2.1.2 apache-airflow-providers-imap==2.2.3 apache-airflow-providers-microsoft-azure==3.8.0 apache-airflow-providers-postgres==4.1.0 apache-airflow-providers-redis==2.0.4 apache-airflow-providers-slack==4.2.3 apache-airflow-providers-snowflake==2.6.0 apache-airflow-providers-sqlite==2.1.3 ### Deployment Astronomer ### Deployment details Localhost instance of Astronomer Runtime 5.0.0 ### Anything else _No response_ ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md) -- This is an automated message from the Apache Git Service.
