report a problem, that is the tooltip of type map.

[DoubleCorner]

Version

5.0.2

Steps to reproduce

option.tooltip = {
  trigger: 'item',
  confine: true,
  formatter: function () {
    const item = mapData[param.dataIndex];
      // TODO echarts 5 bug 会显示上次 tip
      // 没有数据则不展示 tooltip
      if (!item) return null;
  }

Tooltip will show last content. I hope is not displayed. tips: 4.9.0 is ok.

What is expected?

return null will not display last tooltip

What is actually happening?

return null will display last tooltip

I don't understand what do you mean by "show last content"

As shown in the picture, there is no data in Xinjiang. If there is no data, I will return null. But when the mouse hovers over it, it shows the data of Tibet. I was floating in Tibet before, and Tibet has data

[pissang]

But the screenshot shows Tibet is the highlighted area.

那是另一个问题。我用dispatchAction 触发 mapSelect 后，他高亮的颜色是黄色。但是鼠标触发的高亮颜色是那个灰色。而且我已经在 itemStyle 设置 emphasis 的 areaColor 了
