Flexbox changes in FF 34 broke my application layout

We use flexbox heavily for an desktop application like looking web app and it has been working out great.

But with the latest Firefox Developer Edition (35.0a2) the layout does not behave as expected (it grows beyond the viewport): http://jsfiddle.net/yoL2otcr/

This works fine in Firefox 33.1.

I would assume this has something to do with the flexbox changes described here: https://developer.mozilla.org/en-US/Firefox/Releases/34/Site_Compatibility

But sadly I can't yet figure out a way to get the FF 33.x behavior in FF 35.x.

Any help regarding the layout or how to better isolate the problem is appreciated.

Hello Timmp,

Thanks for contacting Mozilla Support. I'm sorry you're seeing issues with Flexbox. To get a more timely answer I would suggest posting it to the Stackoverflow forums. We have some developers who answer posts to the Firefox tag there.
