反馈版本更新4.0后selected: true，失效echarts 饼配置项内容和展示

用3.0版本，建立了一个饼图在series，type：pie 下得data属性里添加了selected: true，增加了选中状态，4.0更新后换成4.0版本的js，selected: true，就失效了。

      option = {
   series: [
        {
            name:'访问来源',
            type:'pie',
            selectedMode: 'single',
            radius: [0, '30%'],

            label: {
                normal: {
                    position: 'inner'
                }
            },
            labelLine: {
                normal: {
                    show: false
                }
            },
            data:[
                {value:335, name:'直达', selected:true},
                {value:679, name:'营销广告'},
                {value:1548, name:'搜索引擎'}
            ]
        },
        {
            name:'访问来源',
            type:'pie',
            radius: ['40%', '55%'],

            data:[
                {value:335, name:'直达', selected:true},
                {value:310, name:'邮件营销'},
                {value:234, name:'联盟广告'},
                {value:135, name:'视频广告'},
                {value:1048, name:'百度'},
                {value:251, name:'谷歌'},
                {value:147, name:'必应'},
                {value:102, name:'其他'}
            ]
        }
    ]
};
