title: How can I get FF 33.x Flexbox behavior in FF 34.x?
body: <p>We use flexbox heavily for an desktop application like looking web app and it has been working out great.</p>
  
  <p>But with the latest Firefox Developer Edition (35.0a2) the layout does not behave as expected (it grows beyond the viewport): <a href="http://tinyurl.com/k6a8jde">http://tinyurl.com/k6a8jde</a></p>
  
  <p>This works fine in Firefox 33.1.</p>
  
  <p>I would assume this has something to do with the flexbox changes described here:

  <p>But sadly I can't yet figure out a way to get the FF 33.x behavior in FF 34 or 35.x.</p>
  
  <p>Any help regarding the layout or how to better isolate the problem is appreciated.</p>
