      data: [
        {
          name: '江苏省',
          value: '1111'
        },

          name: '青海省',
          value: '1121'
        },
        {
          name: '湖南省',
          value: '3456'
        },
        {
          name: '山东省',
          value: '5678'
        },
        {
          name: '安徽省',
          value: '8789'
        },
        {
          name: '云南省',
          value: '600'
        },
      ],
      label: {
        show: true,
        fontSize: '10',
      },
      emphasis: {
        label: {
          show: true,
           fontSize: '20',
        }
      }
    }
  ],
};

Move the mouse to the graphic, display highlight label

Current Behavior

The pie chart is set at the same time series.label.fontsize and Series.emPhasis.label.fontsize. The highlight label when the mouse moves to the graphic is abnormally enlarged. This behavior seems to only appear after the version of 5.2.2

Expected Behavior

The pie chart is set at the same time series.label.fontsize and Series.emPhasis.label.fontsize. The highlight label can be displayed normally

Find the reason, the fontsize attribute should be a number
