Tooltip `stickOnContact: true` throws error on hover from `followPointer: false` to `true`

want the tooltip to show information / icon , when mouseover country I want to display country name.

Works almost, for the first few seconds, but fails when doing mouseover / and inspecting tooltips

Hello @eriksoeb and thanks for reporting the issue.

It looks like the issue is caused by stickOnContact: true. As a workaround you can remove that option or set it to false (default): https://jsfiddle.net/BlackLabel/0xqkrwp2/

it just takes a bit longer to reproduce the error, bit mouse over and tooltip, and especially out in the margins, then the error gets back.
btw there is also a support ticket 21408 on this one.

This is not an exclusive Highcharts Maps problem.
Minimal demo: https://jsfiddle.net/BlackLabel/wxgyuk35/2/

With tooltip.stickOnContact: true hover from a series with tooltip.followPointer: true to a series with tooltip.followPointer: false (or not defined).
In the case of the demo attached here: hover from the point to the column -> error in the console.

By setting **_stickOnContakt:fals, in your minimal demo, I basically get the same information, but fewer error mesages. I am currently not sure if stickOnContact have any impact/function..

I have prepared a workaround for that issue by overwriting one of the tooltip methods. It is inside the IIFE function. If you want to use it, just copy-paste it into your project and everything should work as intended. A similar solution will be used in HC Core.
