Funnel chart not rendered properly when setting borderRadius

[MRezaKarimi]

Expected behaviour

Germany slice should render properly

Actual behaviour

When I set borderRadius, "Germany" slice disappears!. However if I change Germany's value to a number other than 1, problem solves!

Hello @MRezaKarimi and thanks for reporting the issue.

Did you mean funnel or actually a pie chart? Because in the provided demo I can see a funnel chart which is broken anyway and the Germany point is not visible. It looks like the issue is located here (dividing by 0):

highcharts/ts/Series/Funnel/FunnelSeries.ts

Line 481 in ec4c70a

alpha = Math.atan(h / xSide);

FYI @Vazonik

It looks like the issue is located here (dividing by 0):

The issue does not result strictly from division by zero, but from division by 0 when h is 0 too, because 0/0 is NaN when Infinity is expected. The problem can be easily solved by something like this:

alpha = Math.atan(xSide !== 0 ? h / xSide : Infinity);

@Vazonik

Yes you right. I said pie chart by mistake.
