Comienza con la reproducción en el StackBlitz enlazado, particularmente en src/app/cdk-drag-drop-disabled-sorting-example.html, y verifica si el índice cambia al mover elementos entre listas conectadas sin soltarlos. Sigue el manejo de CDK drag-drop para la ordenación deshabilitada y confirma la finalización cuando un elemento vuelve a su lista original en su índice original.
