Error when there is no internal content

[jw56578]

If I only want to open a URL, I shouldn't need a child element in the Popup component.

<Popout url='http://www.google.com' title='Window title' >
 </Popout>

but this creates
invariant.js:39 Uncaught Invariant Violation: ReactDOM.render(): Invalid component element.
