Solid gauge with useHTML in data labels shows wrong series in tooltip

[palhal]

Expected behaviour

Hovering a data label shows a tooltip for the associated series, independent of the dataLabels.useHTML option

Actual behaviour

Hovering a data label shows tooltip for a different series if useHTML = true

Live demo with steps to reproduce

1. Hover the data label (120 km/h) and see that the tooltip shows a different series than the one associated with the label
2. Set useHtmlLabels = false and see that the bug disappears

Product version

Highcharts 10.3.3

Affected browser(s)
