Fix crash if not used box-flex attribute

[niavok]

Hi,

if i use an css file with only :

aa {
    box-flex: 1;
}

and if there is not aa element, i will have the following error :

JavaScript - http://127.0.0.1/fr/contribute/check/process-643b1

Uncaught exception: TypeError: Cannot convert 'node.nodeName' to object

the crash appear in the le 469, executing node.nodeName.toLowerCase(). When it crash, node.nodeName is undefined

I make a small fix but i'm a noob in javascript so there is maybe some regression.

Thanks for flexie.

Thanks for the fix, I've pulled it in manually here: https://github.com/doctyper/flexie/commit/b3ecfdfb9f52c263946da655306bd2b2e5607357

This issue still appears to exist. I have some flex-box elements defined in my CSS stylesheet, and if they don't exist on the actual page, Flexie crashes. This time, it's on line 143 of the de-obfuscated (line 5 of the minimized code). Has anyone else run into this issue?
