title: Always wrap at least two items with flexbox
body: <p>Take a look at <a href="http://codepen.io/HugoGiraudel/pen/LklCv">this example</a></p>
  
  <p>It has a flexbox container with <code>flex-flow: row wrap;</code> to wrap all items. This is almost what I want.</p>
  
  <p>When it starts to wrap, item number 6 wraps to the second line:</p>
  
  <pre><code>1 2 3 4 5
      6
  </code></pre>
  
  <p>But always I want to wrap at least two items when it starts to wrap so you'll never have a single items on a line:</p>
  
  <pre><code>1 2 3 4
    5 6
  </code></pre>
