Cannot update textStyle in tooltip with formatter

[pavelbabenko]

Hi! I'm trying to customize tooltip in series with type: 'custom' using formatted function, but I'm not able to change styles of text

    type: 'custom',
    data: [7000],
    tooltip: {
      formatter: (params: CallbackDataParams) => {
        return `Data: ${params.data}`;
      },
      textStyle: {
        fontSize: 20,
      },
    },

The result:

Yes, this is a problem. custom tooltip in echarts uses html instead of svg, and html is not currently supported in wrn-echarts.

Alternatively, you can select svg rendering in the chart editor in echarts and locate if htm is used by the browser's review element.

We are also in the process of sorting out the relevant currently unsupported features.

This sentence is misrepresented

It may be an issue of echarts.
