The symboloffset of echarts5 is invalid

[Jef-Z]

The symboloffset of echarts5 is invalid, and echarts4 can be used normally. Code example：

option = {
  xAxis: [
    {
      type: 'category',
      data: ['2018-01', '2018-02', '2018-03'],
    },
  ],
  yAxis: [
    {
      type: 'value',
      scale: true,
    },
  ],
  series: [
    {
      name: '满意度',
      type: 'bar',
      data: [
        { value: 73, ranking: 23 },
        { value: 69, ranking: 24 },
        { value: 78, ranking: 12 },
      ],
      markPoint: {
        symbol: 'path://M512 512m-512 0a512 512 0 1 0 1024 0 512 512 0 1 0-1024 0Z',
        symbolOffset: [0, '-100%'],
        data: [{ coord: [0, 73, 23] }, { coord: [1, 69, 24] }, { coord: [2, 78, 12] }],
        itemStyle: {
          normal: {
            label: {
              show: true,
              textBorderWidth: 0,
              textBorderColor: '#f00',
              shadowColor: '#f00',
              color: '#fff',
              formatter: function (params) {
                return params.data.coord[2] + '名';
              },
            },
          },
        },
      },
    },
  ],
};

Please run with echarts5 and echarts4.
