There is a bug in the React 16 beta server renderer, reported by @7rulnik [in the React 16 beta thread](https://github.com/facebook/react/issues/10294#issuecomment-318231160), where the renderer throws an exception when `style` is included and NODE_ENV is `production`.

Given this file:

```
// index.js
const React = require('react')
const ReactServer = require('react-dom/server')
const foo1 = React.createElement("div", {
  className: "sign-link",
  id: "sign-layout-link",
  style: { position: 'absolute' }
});

console.log(ReactServer.renderToString(foo1))
```

If you run `NODE_ENV=production node index.js`, you'll get:

```

Weirdly, dev mode does **not** throw an error.
