I encountered an issue when wanted to propagate tags from task definition for run-task because of https://github.com/aws-actions/amazon-ecs-deploy-task-definition/issues/249#issuecomment-1538851215. The describe-task-definition can return tags, but it need to be merged to the task definition, which is not easy to do with cli or in amazon-ecs-render-task-definition (see https://github.com/aws-actions/amazon-ecs-render-task-definition/issues/317).
