### Anything else?

_No response_

Inizia con l’esempio Angular CDK drag-drop all’indirizzo angular.dev/guide/drag-drop#restrict-movement-within-an-element e riproduci il problema su uno schermo touch usando il gesto pinch descritto. Traccia la gestione di touchmove dell’elemento trascinabile e l’intervento cancelable=false; il lavoro è completato quando l’elemento rimane entro i propri limiti durante il gesto senza generare l’errore segnalato.
