描述

### 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

autocomplete does not behave like other material compnents like menu or select - those lock the scrolling of the underlying div/html/body.

### Reproduction

Steps to reproduce:
1. https://material.angular.io/components/select/overview
2. open autocomplete and scroll on body

### Expected Behavior

scroll is locked

### Actual Behavior

scrolling is enabled - inconvenient behavior between material components, resulting in multiple issues e.g. z-index or if a container for scrolling is used the autocomplete panel does not scroll.

### Environment

- Angular: 15.1.1
- CDK/Material: 15.1.1
- Browser(s): all
- Operating System (e.g. Windows, macOS, Ubuntu): all

调研方向

首先在链接的 Material select 概览中复现该问题,将 autocomplete 的滚动与 menu 或 select 的行为进行比较。在 Angular components repository 中跟踪 autocomplete 及相关 overlay 的行为;当 autocomplete 面板打开时,底层 div、html 或 body 的滚动能够始终保持锁定,即表示完成。
