Research direction
The issue requests a new event emitter on the cdkTextareaAutosize directive to notify when the textarea height changes, improving efficiency over keyup checking. The relevant code is likely in the CDK's text field module, specifically the autosize directive. Examine the existing implementation and consider adding an @Output() event that fires after the height adjustment logic.
