React 16.0.0 with SSR & [lazysizes](https://github.com/aFarkas/lazysizes) 4.0.1.

Trying to use the ["the noscript pattern"](https://github.com/aFarkas/lazysizes#the-noscript-pattern) to lazy load images with [lazysizes](https://github.com/aFarkas/lazysizes) but I'm seeing this:

> Warning: Expected server HTML to contain a matching &lt;img&gt; in &lt;noscript&gt;.

Image component render method:

```js
render () {
    const { cdn, url, width, height } = this.props

    if (!url) return null

    const noScriptImgProps = {
      src: `${cdn}${url}`,
      className: classNames('product-image'),
      width,
      height
    }

    const imgProps = {
      'data-src': `${cdn}${url}`,
      className: classNames('product-image', 'lazyload'),
      width,
      height
    }

    return (
      <span>
        <noscript>
          <img {...noScriptImgProps} />
        </noscript>
        <img {...imgProps} />
      </span>
    )
  }
```

Does React have an issue with `noscript` tags..?
