Incorrect behaviour of flex-container with column flow

Dear Sir or Madam,

First of all, I want to express my gratitude for your work!

Recently, I was working on flexbox layout. Here is what I have got: http://jsbin.com/xojopa. ".section" element uses flexbox column layout. As you can see, ".card"s do not extend parent ".section" element. Although, according to W3C spec (http://www.w3.org/TR/css-flexbox-1/#flex-flow-property) it should. I mean, a ".section" element has it's height and it specified that elements should be wrapped. It means, that in the example I provided, ".section" element should be stretched according to it's content. The same as if we had normal, horizontal flow and parent element stretched according to it's content.

I have to admit that W3C doesn't say anything explicitly about this case. However, according to the picture they provide (http://www.w3.org/TR/css-flexbox-1/images/flex-flow2.svg) current behaviour (the one I provided in the example) is incorrect.
