echarts 制作钻取地图，向下钻取时没有过渡动画了？

Version

5.0.1

Steps to reproduce

先绘制中国地图
点击某个省之后，重新注册对应省的地图数据并再次调用 setOption

What is expected?

能像 4.x 版本一样向下钻取地图时候有过渡动画效果

What is actually happening?

没有过渡动画效果

const myCharts = init(document.getElementById(id) as HTMLDivElement);
    let currentGeoJson: GeoJsonCity = GeoChina as any; // 当前绘制数据

    // 监听点击事件
    myCharts.on('click', params => {
      const ev = params as EchartEvent
      const item = currentGeoJson.features.find(geo => geo.properties.name === ev.name)
      get_geoJSON_byCode(item?.properties.adcode as string, {
        listen(load) { load ? myCharts.showLoading() : myCharts.hideLoading() }
      }).then(geoJson => {
        currentGeoJson = geoJson;
        const { properties } = geoJson.features[0]
        drawMap({
          charts: myCharts,
          name: `${properties.name}-${properties.adcode}`,
          geoJson,
        });
      })
    });

    // 绘制地图函数
    function drawMap({
      charts,
      name = '中国',
      geoJson = GeoChina as any,
    }: {
      charts: ECharts;
      name?: string;
      geoJson?: GeoJsonProvice | GeoJsonCity;
    }) {
      if (!getMap(name)) {
        // 向 echarts 注入地图数据；name 为 series 中使用时候的标识
        registerMap(name, geoJson as any);
      }

      // 绘制地图
      charts.setOption({
        geo: {
          map: name,
          zoom: 1.1999,
          animation: true,
          animationDuration: 1999,
        },
      });

      return charts;
    }

    drawMap({ charts: myCharts });

  /**
   * 根据 adcode 获取 geo 数据；localhost 会被反爬 - 用 proxy 或者改 host
   * @param code adcode
   */
  export async function get_geoJSON_byCode(
    code: string | number,
    { full = true, listen = (bool: boolean) => { } } = {},
  ): Promise<GeoJsonCity> {
    listen(true);
    const res = await fetch(proxy(`/areas/bound/geojson?code=${code   (full ? '_full' : '')}`))
    listen(false);
    return res.json()
  }
