[WASM] Exception if SfChart.Behaviors does not contain a ChartSelectionBehavior #18

Open mikernet opened 2 years ago

mikernet commented 2 years ago

If I put a chart on a page (I used BarSeries) without a ChartSelectionBehavior added to SfChart.Behaviors then it crashes on WASM with the following exception:

It does not do this on UWP.

P.S. Same thing happens if an AreaSeries chart does not have a ChartZoomPanBehavior added.
