title: Highmaps in Typescript: Maps not being dipslayed
body: <p>I am trying to use a highmap of the highcharts package in typescript using react. However, it does not display the map at all. </p>
  
  <p>See a live demo here: <a href="https://codesandbox.io/s/o9nokjr6vz" rel="nofollow noreferrer">https://codesandbox.io/s/o9nokjr6vz</a> </p>
  
  <p>It is related to this option:</p>
  
  <pre><code>Highcharts.mapChart("investment", {
    chart: {
      map: "countries/de/de-all"
    },
  </code></pre>
  
  <p>What am I missing?</p>
