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

Start by reproducing the issue with the provided Angular template using *cdkVirtualFor, Signals, and removal from orderColumn().orders, then compare it with *ngFor. Trace the virtual-scrolling update path and verify that removing an element causes the corresponding rendered item to leave the screen.
