title: contentEditable breaks page up down buttons in firefox
body: <p>Does anyone know how to fix (or what causes) the page up/down bug in FF when contentEditable is present on a div?</p>
  
  <p><strong>See an example</strong>
  Navigate to <a href="http://perplexed.co.uk/993_contenteditable_cross_browser_wysiwyg.htm" rel="nofollow noreferrer">contentEditable article</a> with FireFox (3 or 3.5) and use the Page Up/down arrows on your keyboard. You should be unable to scroll to the bottom of the page, and it should appear to flicker and jump back up.</p>
