Hi

I'm adding a dblclick handler, e.g as follows (from Vue snippet):

this.chart1.hostElement.addEventListener('dblclick', (e) => {
var hti = this.chart1.hitTest(e);
console.log("hti", hti);
console.log("e", e)
console.log("ce", hti.chartElement);

    if(hti.chartElement == wjcChart.ChartElement.PlotArea && this.chart1.selection != null)
    {
      this.drilldown(this.chart1);
    }
  });

the hit test, when clicking on a column chart bar is returning a hit.chartElement of 0, which is the enum for PlotArea. I would have expected this to return 7, the enum for Series (as per here: https://www.grapecity.com/wijmo/api/enums/wijmo_chart.chartelement.html#series )

The console output I get from above is:

_hti HitTestInfo {_pointIndex: 86, _chartElement: 0, _chart: FlexChart, _pt: Point, _series: Series, …}
e MouseEvent {isTrusted: true, screenX: 939, screenY: 634, clientX: 939, clientY: 563, …}
ce 0

So, you can see that ce = 0, when I'm definitely click on a bar in a column chart.

I'm getting around this by adding in the selectionMode = 'Point' and handling if this.chart1.selection != null currently, but I'm a bit worried that if this is a bug and I upgrade this will not work. I'd appreciate

Thanks
Brian
