HighchartsReact does not render properly in custom

Question

I'm using HighchartsReact and I'm struggling to render my charts properly inside a simple tab implementation. Every time I change tabs, the charts get "stuck" on the previous rendering and never refresh. Here is the sample code. Thanks!

const chart1 = {
  "title": { "text": "Chart 1" },
  xAxis: { type:'datetime' },
  "series": [
    { "name": "ONe line", "data": randData1 },
    { "name": "Another LIne", "data": randData2 }
  ],
  chart: { events: { load: function(){} } }
}

const chart2 = {
  "title": { "text": "Chart 2" },
  "series": [
    { "name": "First Line", "data": randData3 },
    { "name": "Second Line", "data": randData4 }
  ],
  chart: { events: { load: function(){} } }
}


const TheChart = ({ chartData }) => <HighchartsReact highcharts = { Highcharts } options = { chartData } />

const tabHeaders = [
  'Chart One', 
  'Chart Two'
];
const tabContent = [
  <TheChart chartData={ chart1 } />,
  <TheChart chartData={ chart2 } />
 ];

const tabsProps = { tabHeaders, tabContent };
ReactDOM.render(<Tabs { ...tabsProps } />, document.getElementById('root'));

Please take a look at this example: https://codesandbox.io/s/18836vk8oj - React does not switch components from the same class, the first component is only updated. Creating a new class for the second component is one of the ways to solve the problem: https://codepen.io/anon/pen/xmqvmX?editors=0010

const tabContent = [
  <div>...</div>,
  <TheChart chartData={ chart1 } />,
  <TheChart2 chartData={ chart2 } />
];

Updating component with a chart fires chart.update(), so for example if you want to change xAxis.type you must change it in two configurations:

chart.update({
    series [...],
    xAxis: {
        type: 'datetime'
    }
});

chart.update({
    series [...],
    xAxis: {
        type: 'linear'
    }
});

Another issue here is that Highcharts for performance mutate series config object: https://github.com/highcharts/highcharts/issues/9732 - so you need create a deep copy of your options or change the structure of the project.
