bug(CdkTextareaAutosize): Textarea does not scroll to active line

### Is this a regression?

- [x] Yes, this behavior used to work in the previous version

### The previous version in which this bug was not present was

18

### Description

Hello,

Is there currently a solution or planned fix for this issue?

As described in [issue 30841](https://github.com/angular/components/issues/30841)
, when using the textarea with cdkTextareaAutosize, the component does not automatically scroll to keep the cursor in view once the content exceeds the maxRows. This makes the textarea very difficult to use.

The problem occurs on Google Chrome (but not in Firefox).

It appeared starting from Angular Material v19.

In v18, the behavior was correct: https://v18.material.angular.dev/cdk/text-field/overview

From v19 up to the current version, the bug is reproducible in Chrome: https://material.angular.dev/cdk/text-field/overview

Thank you for your help and clarification.

2. when more that 5 lines are added, cursor deapear and we are typing in the hidden part of the textarea (we don't see what we are typing anymore)

Do the same on Firefox:
- the textarea scrolls automatically to active line

### Expected Behavior

The textarea does not scroll automatically to the active line on google chrome

The textarea should scroll automatically to the active line on all nagigators

Tái hiện vấn đề bằng ví dụ StackBlitz được liên kết trong Chrome, sau đó so sánh hành vi với Firefox và các ví dụ Angular Material v18 và v20. Nhập hơn năm dòng vào textarea và xác minh rằng con trỏ vẫn hiển thị trong khi nhập; bản sửa được hoàn tất khi Chrome cuộn đến dòng đang hoạt động như Firefox.
