Descrizione

### Command

serve

### Is this a regression?

- [ ] Yes, this behavior used to work in the previous version

### The previous version in which this bug was not present was

_No response_

### Description

Changes will no longer be recognized if you remove and re-add same component.

### Minimal Reproduction

Removing and re-adding the import of the component (`import { TestComponent } from ‘./test/test.component’`), the component in the `imports` array and in the template (``) leads to that no further changes to this component are recognized.

### Anything else relevant?

After clearing the Angular cache with `ng cache clean` and restarting the dev server with `ng serve` it works again.
So probably a caching bug.

Direzione di ricerca

Inizia con le riproduzioni StackBlitz collegate ed esegui il comando `serve` usando la sequenza di rimozione e nuova aggiunta descritta nell’issue. Confronta il comportamento prima e dopo `ng cache clean`; il lavoro è completato quando le modifiche successive al componente aggiunto nuovamente vengono riconosciute senza svuotare la cache di Angular né riavviare il server di sviluppo.

Scritto dal modello di indicizzazione a partire dal testo della issue.
