Internal note:

It works fine after changes in the code and back to previous state.

------ EDIT -------

scrollablePlotArea changes chart DOM and separate some parts to different divs like:

<div id="container">
   <div id="highcharts-....." class="highcharts-container">
   </div>
</div>

to:

<div id="container">
   <div class="highcharts-fixed">
   </div>
   <div class="highcharts-scrolling">
      <div class="highcharts-inner-container">
          <div id="highcharts-....." class="highcharts-container">
          </div>
      </div>
   </div>
</div>

Current Fullscreen.prototype.open implementation affects only on the "highcharts-inner-container". There will be needed some additional condition to affect on other parents when scrollable is applied.

Current workaround only for the vertical scroll (description inside): https://jsfiddle.net/BlackLabel/1pvLn49e/
