URL: https://github.com/apache/incubator-echarts/issues/10394
 
 
   ### Version
   4.2.0-rc.2
   
   ### Steps to reproduce
       const seriesData = _.map(data, item => {
           const itemStyle = hightLight === item.timeUnit ? {color: '#f00'} : {color: 'pink'};
           maxValue = maxValue < item.value ? item.value : maxValue;
           return {
               name: item.timeUnit,
               value: item.value,
               itemStyle: itemStyle,
               emphasis: {
                   itemStyle
               }
           };
       });
   ...
     this.chartRef.current.chart.on('click', item => {
               this.resetSeriseData(item.name); // 重新修改数据样式
   }
   
   ### What is expected?
   在hover某个柱子是单击该柱子，然后重设该柱子展示样式itemstyle,希望能正常render新样式
   
   ### What is actually happening?
   没有展示新样式
