Doesn't work with mapped SortableItems

This works:

``` js
render() {
return

React


Angular


}
```

This doesnt:

``` js
function renderItem(n, index) {
return {n}
}

render() {
return
{items.map(renderItem)}

}
```

And by doesn't work, I mean nothing is rendered within sortable.

If I render the `{items.map(renderItem)}` outside of ``, it works...

Very odd.

Start with the render examples in the issue and compare how Sortable receives direct DemoHOCItem children versus the children returned by items.map(renderItem). Check whether the mapped children render inside Sortable while confirming the same items render outside it; done means the mapped items appear within Sortable. The issue does not name files or tests, and its old, lengthy comment thread suggests it may not receive timely guidance.
