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?

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.

Hi @jsokol, We are currently during the vacation period, so all of the fixes/releases are currently on hold. For now, you need to use the workaround. Sorry for the inconvenience :(

Totally understand you guys being on vacation and I'm not pushing for an immediate fix. I guess what I'm trying to figure out is when you'll be off vacation and fixes/releases are no longer on hold so this can be addressed? Are we talking days?
Weeks? Months? What kind of priority will this be given when you are back? Thanks.

@jsokol, the fix is already in review, so in terms of development, there is not much to take into consideration. It is a matter of the date of the next release, which I would expect to be near the end of August.

This helps a ton! Thank you!
