[Feature Request]: Stacked Column Series - Getting the series that was clicked from the event args in seriesMouseLeftButtonDown

[norikois]

Which component(s) are affected?

Other/unknown (please specify in the description)

Description

In IgcDataChartComponent with IgcStackedColumnSeries, it would be good to be able to get the clicked series from event args in seriesMouseLeftButtonDown.

Reproduction

1. Start the attached sample.
2. Click one of the column fragments.
   -> Observe the brower dev tool's console.

Actual:
Series information, such as title, valueMemberPath, etc., cannot directly be obtained from the event args.

Expected:
Series information can directly be obtained from the event args.

Workaround

stackedColumnChart1.seriesMouseLeftButtonDown = (s: IgcSeriesViewerComponent, ev: IgcDataChartMouseButtonEventArgs) => {
    console.log('Stacked Column Chart 1 seriesClick');
    console.log(`[Item] ${JSON.stringify(ev.item)}`);

    // It would be good to be able to directly get the series that was clicked from the event args.
    // Actually, ev.series is IgcColumnFragmentComponent
    // and it neither exposes APIs to get access to its corresponding IgcStackedColumnSeries nor can be casted to it.
    console.log(`[Series] Title: ${ev.series.title}, ValueMemberPath: ${ev.series.valueMemberPath}`);

    // Workadound
    // const dataSourceName = sampleData1.includes(ev.item) ? 'sampleData1' : sampleData2.includes(ev.item) ? 'sampleData2' : 'unknown';
    // console.log(`[Data Source] ${dataSourceName}`);
    // switch(dataSourceName) {
    //     case 'sampleData1':
    //         console.log(`[Series Info] Title: ${stackedColumnValue1Series.title}, ValueMemberPath: ${stackedColumnValue1Series.valueMemberPath}`);
    //         break;
    //     case 'sampleData2':
    //         console.log(`[Series Info] Title: ${stackedColumnValue2Series.title}, ValueMemberPath: ${stackedColumnValue2Series.valueMemberPath}`);
    //         break;
    //     default:
    //         console.log('Unknown data source');
    // }
}

Is this a regression?

No or unsure. This never worker, or I haven't tried before.
