Wrong max extreme for the selection event in column charts about highcharts

[hubertkozik]

Hi @ollivih! Thank you for reporting the issue. The axis max value is correct, but the min value is wrong. This is a regression.

Demo with axis min/max logging: https://jsfiddle.net/BlackLabel/jbx4ydmh/

I've prepared a workaround for this issue. If you want to use it in your project just copy-paste the IIFE function to your project.

Internal note:
Workaround is changing the floor and ceiling by adding/subtracting the minPointOffset.

I feel that also the max value is incorrect with some selections.

For example in this selection, the max value seems correct (1):

But in this selection, where the max is in the same place as in the previous, it gives 1.5 as the max value:

You're right @ollivih! My bad, sometimes the max values are incorrect also, but the workaround from my previous post is fixing max values also.
