[GitHub] [airflow] edwardwang888 commented on issue #16824: Initiating `mark success/failed` operation causes UI border to disappear for task instances with no status

   Upon further investigation, this appears not to be primarily a UI bug, but rather an issue with the existence of task instances in the `task_instances` table.
   
   It seems that if a task instance does not exist in the `task_instance` table, the UI will display it as `no_status` (with the black border). However, upon initiating a `mark success/failed` operation, the non-existent task instances for that DAG run are created in the `task_instance` table with `state` = `NULL`. This does not get identified as a `no_status` task instance, and thus is not drawn properly.
