Description

Reproduction

Steps to reproduce:

  1. Install Firefox mobile (https://play.google.com/store/apps/details?id=org.mozilla.firefox, versionName=68.4.2, versionCode=2015676155)
  2. Navigate to https://material.angular.io/components/input/examples (currently version 8.2.3)
  3. Scroll down to the the 'Auto-resizing textarea' section
  4. Tap in the 'Autosize textarea' box
  5. Type a few characters

Expected Behavior

Characters appear exactly as typed

Actual Behavior

  • Extraneous characters appear.
  • Looks like the Firefox mobile browser and Angular Material are fighting each other, causing extra characters to appear

Environment

Contributor guide

Research direction
Investigate the autosize directive or textarea event handling in Angular Material to identify why Firefox mobile inserts extra characters. Compare behavior with desktop Firefox and Chrome. Look for platform specific workarounds.
