Description
### 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.

[Problem also in V19](https://stackblitz.com/edit/stackblitz-starters-2h7zbv?file=src%2Ftest%2Ftest.component.ts,src%2Fmain.ts)

### 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.
