See original GitHub issue

As soon as I add matTextareaAutosize to a textarea it duplicates characters

What is the expected behavior?

Only the typed characters appear

What is the current behavior?

Typed text “Hello” Text in textarea: HelloH

What are the steps to reproduce?

Type “Hello” into the textarea https://angular-bv2wxj.stackblitz.io https://stackblitz.com/edit/angular-bv2wxj?file=app%2Fform-field-overview-example.html

this is a fork of the sample of simple input fields https://stackblitz.com/angular/kdpyvloydqv Only change:

<mat-form-field>
  <textarea matInput placeholder="Textarea" **matTextareaAutosize**></textarea>
</mat-form-field>

What is the use-case or motivation for changing an existing behavior?

Angular apps should work on any modern browser.

The bug is reproducible with Firefox 58, too. That is not beta.

I agree that it could be a but with Firefox mobile, since textarea with matTextareaAutosize works fine in many other browsers. But anyhow it would be great, if someone yould analyse what is different on Firefox mobile.
