title: How do I stop a textarea from scrolling to the top whenever I change its value
body: <p>I'm making something where a textarea gets more and more text appended. In firefox, the textarea scroll back up to the top each time.
  I currently have something like <code>textarea.scrollTop=1000000;</code> to scroll it back down each time it changes, but it still goes up to the top for a very short time.
  Is there any way to stop it doing so?</p>
