1. Copy the following code in the echart demo: http://echarts.baidu.com/examples/editor.html?c=sunburst-simple to show the color in the tooltip. Note copy the code in the "options" part.

   tooltip: {
   formatter: function (info) {
   let tooltipHtml=<div style='width: 38px; height: 5px; border-radius: 20px; background-color:${info.color};'> </div>
   return tooltipHtml;
   },
   },

2. move the mouse to the "cousin Jenny" area, which should show the "blue" color bar in the tooltip, but it is not.

3. copy the same code in another sunburst demo: http://echarts.baidu.com/examples/editor.html?c=sunburst-drink, its show the right color bar.

最后咋解决的？

@weizhanzhan 测试了下，我认为这个问题在当前ECharts版本中应该已经被解决了。
