colorAxis with dataClasses does not allow legendItemClick

[KacperMadej]

Example: http://jsfiddle.net/rh8t755d/

Clicking on legend items does not trigger legendItemClick event.

This is because legendItemClick is defined on the series, while the colorAxis is not related to any series.

Any ideas how one could code around this ?

@the-codepunker Here's a workaround - added wrapper for legend item setVisible function that runs on each legend item click and is generated in getDataClassLegendSymbols of ColorAxis.prototype.

The issue is still relevant (v11.2.0).

[KacperMadej]

The issue is for the color axis and is not limited to Highcharts Maps.
