Right now, the view loops and retrieves the mapped instances of all the expansions of a single task, that means that if a DAG created 100 expansions of a task instance, it loops through all the 100 expansions in order to retrieve the status of the 100! This makes the loading of that view very slow, and it is also not needed, applying the same logic, we only need to retrieve the mapped instances of one of the expansions to get the status of the rest (Since they all share the same Task Id). --- **^ Add meaningful description above** Read the **[Pull Request Guidelines](https://github.com/apache/airflow/blob/main/CONTRIBUTING.rst#pull-request-guidelines)** for more information.
