edwardwang888 opened a new issue #16877: URL: https://github.com/apache/airflow/issues/16877
**Description** Task instances in manual runs do not display with a border, except when the task instance is non-existent (after adding tasks to an existing DAG). Hence, when an _existing_ task instance is cleared, it is displayed without a border, causing it to disappear into the background. To be consistent, existing task instances that are cleared should also be drawn with borders. Here, `task2a` and `task2b` are newly-added tasks and have `no_status`. They are displayed with borders:  Afterwards, `task1a` and `task1b` are cleared and are drawn without borders:  **Use case / motivation** To prevent the task instances from disappearing into the background. **Are you willing to submit a PR?** Yes, but would need ramp-up time as I am new to front-end. **Related Issues** Split from #16824. -- This is an automated message from the Apache Git Service.
