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

[BUONJG]

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

18

Description

Hello,

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

As described in issue 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.
