Required css not added to head since upgrade to latest

Hi,

I recently upgraded hjs-webpack to the latest version. However since the upgrade my CSS files which are imported into the js are not being added to the head.

Here is my config:

const config = getConfig({
  in: 'src/index.js',
  out: 'build',
  output: {
    filename: "js/bundle.[name].[hash].js",
    cssFilename: "css/styles.[hash].css",
    hash: true
  },
  port: 8080,
  clearBeforeBuild: true,
  html: function (context) {
    return {
      'index.html': context.defaultTemplate({
        head: `
      <link rel="stylesheet" href="//cdnjs.cloudflare.com/ajax/libs/semantic-ui/2.2.12/semantic.min.css"></link>
      <script src="https://cdn.ravenjs.com/3.22.1/raven.min.js" crossorigin="anonymous"></script>
      `
      })
    }
  }
})

output:

<!doctype html>
<head>
<meta charset="utf-8"/>
<meta name="viewport" content="width=device-width, initial-scale=1, user-scalable=no"/>
<link rel="stylesheet" href="//cdnjs.cloudflare.com/ajax/libs/semantic-ui/2.2.12/semantic.min.css"></link>
<script src="https://cdn.ravenjs.com/3.22.1/raven.min.js" crossorigin="anonymous"></script
</head>
<body>
<div id="root">
</div>
<script src="/js/bundle.main.0ed91bc410623fb474dc.js"></script>
</body>
