See http://jsfiddle.net/3zd7yspg/1/ Wraps properly in Chrome and Firefox. Does not wrap in Safari or Webkit nightly build. This property appears to be ignored: -webkit-flex-wrap: wrap;
Here is a working demo of flex-wrapping in Safari 8.0. http://codepen.io/tzi/full/xGdNEK/
The fiddle of Daniel doesn't work because of the `min-width` set on the flex items. So it's a duplicate ticket of #136041 https://bugs.webkit.org/show_bug.cgi?id=136041
