Shared Tooltip should render multiple datapoints for the respective variable.

Actual behaviour

Tooltip does not render at all and the following error is thrown in the console.

Thanks @rw-jchartis for reporting this issue!
It's a regression, which popped up in the latest version v10.2.0.

The problem is with a this context which should be a polar composition instead of series.
Possible culprit:

highcharts/ts/Series/PolarComposition.ts

Lines 147 to 151 in e23cfb7

	searchPoint: (
	PolarSeriesComposition['kdByAngle'] extends true ?
	PolarAdditions['searchPointByAngle'] :
	Series['searchPoint']
	);

Workaround (pass a correct context): https://jsfiddle.net/BlackLabel/x64hetLn/

point = s.searchPoint.call(s.polar, e, compareX)

Same problem here. Sorry for the duplicate. Is there a way to fix this problem temporarily?

Thank you so much.

Any idea when this bug fix will go live? We would prefer not to implement the aforementioned workaround if this will be updated sooner, rather than later. Thanks.
