bug(MatAutocomplete): BlockScrollStrategy doesn't work with cdkScrollable

### 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

Using `BlockScrollStrategy` on `MatAutocomplete` does not work unless the scroll container is the document itself.
I've added `cdkScrollable` to the scroll container, and `CloseScrollStrategy` and `RepositionScrollStrategy` do work, but not `BlockScrollStrategy`.

### Reproduction

1. https://angular-scroll-block.stackblitz.io
2. Use Ctrl+Space inside the input field and scroll the scroll-container.

Working example with the scroll in the document:
1. https://angular-scroll-block-works.stackblitz.io
2. 2. Use Ctrl+Space inside the input field and scroll the document.

### Expected Behavior

Scroll should be blocked when using `BlockScrollStrategy`

### Actual Behavior

Scroll is not blocked when using `BlockScrollStrategy`

### Environment

Beginne damit, das Verhalten im verlinkten angular-scroll-block.stackblitz.io-Beispiel zu reproduzieren, und vergleiche es mit dem funktionierenden document-scroll-Beispiel. Lies die Einstiegspunkte von MatAutocomplete und BlockScrollStrategy und überprüfe anschließend, dass das Scrollen des cdkScrollable-Containers blockiert wird, während das Autocomplete geöffnet ist, ohne die anderen Scroll-Strategien zu beeinträchtigen.
