Problem with tooltip formatter in unit tests

[Paweł Potaczek]

I am using JEST and RTL for writing unit tests. I can see charts being rendered inside tests when I check below assertion it is true
expect(container.getElementsByClassName("highcharts-point").length).toBeGreaterThan(0)

when I trigger event on the highcharts-point I also see highcharts-series-hover also gets applied which means hover was successful but the issue is formatter function is not triggered from tooltip options for highcharts due to which tooltip is not displayed and I am not able to test further assertions. can someone help what am I missing here?

tooltip: {
  useHTML: true,
  crosshairs: [{
      dashStyle: "dash"
    }, {
      dashStyle: "dash"
    }],
  shared: false,
  snap: 15,
  formatter(): string {
    return getTooltipData(this);
  }
}
    ```

Hi @abhirocks550,

Thank you for contacting us!

It's hard to guess what might be causing the problem, so could you reproduce the issue in some minimal project and add it here as a .rar archive?

Best regards!
