react-markdown-loader Invalid babel syntax

I'd like to display some code samples within the page, not actually render it. But I'm getting an error.

I'm not quite sure if the problem is in this loader or not. When I add the following to a markdown file that is processed through this loader and then through babel, I get a BabelLoaderError: SyntaxError: Unexpected token (46:227) error.

```js
function Sample () {
  return 'hi'
}
```

Here is the full error:

ERROR in ./src/elements/Hello/readme.md
