* This is a utility component to wrap around the nodes we are
* passing in to `mount()`. Theoretically, you could do everything
* we are doing without this, but this makes it easier since
* `renderIntoDocument()` doesn't really pass back a reference to
* the DOM node it rendered to, so we can't really "re-render" to
* pass new props in.
