I'm a bit late on this one, but this is a known issue of Highcharts. Instead of using the select event, use the selected and unselected events. There is a subtle difference here, as using select will often not fire directly after a click. These two events however are more reliable.

In the current version of the Highcharts (Highcharts Basic v7.2.1) everything is working properly.
