title: using Highcharters in R with Shiny, control highstock chart height failed
body: <p>I called highchart with height parameter to make a taller chart successfully in RStudio:</p>
  
  <pre><code>chart &lt;- highchart(type = "stock", height=800, ...)
  </code></pre>
  
  <p>When in Shiny, the chart shown up but ignore the height parameter. Is there any way to fix it ?</p>
