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..?


switch (type) {
    case 'button':
    case 'input':
    case 'select':
    case 'textarea':
      return !!props.autoFocus;
  }
  return false;
}
export * from 'shared/HostConfigWithNoPersistence';
export function getRootHostContext(
  rootContainerInstance: Container,
): HostContext {
  let type;
  let namespace;
  const nodeType = rootContainerInstance.nodeType;
  switch (nodeType) {
    case DOCUMENT_NODE:
    case DOCUMENT_FRAGMENT_NODE: {
      type = nodeType === DOCUMENT_NODE ? '#document' : '#fragment';
      let root = (rootContainerInstance: any).documentElement;
      namespace = root ? root.namespaceURI : getChildNamespace(null, '');
      break;
    }
    default: {
      const container: any =
        nodeType === COMMENT_NODE
          ? rootContainerInstance.parentNode
          : rootContainerInstance;
      const ownNamespace = container.namespaceURI || null;
