bug(Virtual scrolling + Signals): When removing an element from the array it is not removed from the screen

### 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

When trying to use Virtual Scrolling with Signals when removing element, it is not removed from the screen. The bug only occurs using `*cdkVirtualFor`. If you use `*ngFor` the element is removed correctly.

### Reproduction

Ex:

HTML:
```

```

TS:
```
export type OrderColumn = { orders: Order[], total: number, page: number };
orderColumn: Signal;

```

### Expected Behavior

I expected that when removing an element from the orderColumn().orders array it would exit the screen.

### Actual Behavior

When removing an element, it continues to be rendered on screen.

### Environment

```

Beginne damit, das Problem mit dem bereitgestellten Angular-Template unter Verwendung von *cdkVirtualFor, Signals und dem Entfernen aus orderColumn().orders zu reproduzieren, und vergleiche es anschließend mit *ngFor. Verfolge den Aktualisierungspfad des virtuellen Scrollens und überprüfe, dass durch das Entfernen eines Elements das entsprechende gerenderte Element den Bildschirm verlässt.
