Highcharts part missing while moving mouse

Question

I use Highcharts to visualize my data. Recently I found that when I move my mouse around the chart, part of the chart will be missing. Looks like it happens randomly and I have no idea what triggers it.

I created a jsfiddle example here with js codes below:

Highcharts.chart('container', {

  credits: {
    enabled: false
  },
  title: {
    text: "资产结构"
  },
  tooltip: {
    enabled: true,
    shared: true
  },
  xAxis: [{
    categories: ['2014年', '2015年', '2016年', '2017年半年度'],
    crosshair: true
  }],
  yAxis: [{
    title: {
      text: "金额(万元)",
      style: {
        color: "#33C4FF"
      }
    },
    labels: {
      format: "{value:,.0f}",
      style: {
        color: "#33C4FF"
      }
    },
    opposite: false
  }, {
    title: {
      text: "比率(倍)",
      style: {
        color: "#99FF33"
      }
    },
    labels: {
      format: "{value}",
      style: {
        color: "#99FF33"
      }
    },
    opposite: true
  }],
  plotOptions: {
    area: {
      stacking: 'normal'
    },
    series: {
      shadow: true
    }
  },
  legend: {
    enabled: true,
    backgroundColor: Highcharts.theme && Highcharts.theme.legendBackgroundColor || '#FFFFFF'
  },

  series: [{
    name: "流动资产",
    yAxis: 0,
    data: [{

});

#container {
  min-width: 310px;
  max-width: 800px;
  height: 400px;
  margin: 0 auto
}

<div id="container"></div>

Open it in Microsoft edge and then move the mouse around the yellow point on category '2016年'. Keep doing that for about 5 seconds, you should be able to see the issue.

I also record a video about the issue here: youtube link, any words are appreciated.

-- Update -- I tested the jsfiddle example on Microsoft Edge 40.15063.674.0, it works well. In the youtube video, the version of Edge is 41.16299.15.0, I am not sure if this is related.
