1439259 - textarea duplicates characters

Status: RESOLVED WORKSFORME

(Firefox for Android Graveyard :: General, defect, P5)

Description

[christian]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.13; rv:59.0) Gecko/20100101 Firefox/59.0
Build ID: 20180215111455

Steps to reproduce:

I created a web app with Angular Material components
Code Example:
https://stackblitz.com/edit/angular-bv2wxj

The behavior is caused by the instruction matTextareaAutosize. That should make the textarea grow with its content
<textarea matInput placeholder="Textarea" matTextareaAutosize></textarea>

URL to run the web app:
https://angular-bv2wxj.stackblitz.io/

type "Hello" in the textarea


Actual results:

As result it shows "HelloH"


Expected results:

It should show "Hello"

I filed a bug for Angular Material before. But they think it is not their fault, since the code works fine with any desktop browser including Firefox and with Chrome on Android, too. It seems to be specific to Firefox on Android.
