Research direction
The bug occurs when switching DAG versions in the graph view. Investigate the React component responsible for rendering the graph (likely in airflow/ui/src/). Check if the version change triggers a re fetch of graph data and if the component's state is updated accordingly. Look for missing useEffect dependencies or improper handling of async data. Also verify the backend API endpoint for graph data handles version parameter correctly. Review comments in the issue for any additional clues.
