title: Content Editable DIV is not taking any space randomly in Firefox and IE
body: <p>Content Editable DIV is not taking any space randomly in Firefox and IE. Sometimes it works fine, but often apparently starts ignoring the white-space key.</p>
  
  <p>Leaving the window open for a while when it works fine worsens it further - it starts showing the same problem - ignoring the white key space.</p>
  
  <p>The problem is only with typing. When paste text having spaces, it is rendered properly, even if I was not able to key in White Spaces.</p>
  
  <p>It works consistently fine in Google Chrome.</p>
  
  <p>I'm using "white-space: pre", but also tried with "white-space: pre-wrap". No help.</p>
  
  <p>I have recent version of Firefox (40.0).</p>
