SfChart - NullRefException by ChartZoomPanBehaviorHelper

Dear Support,

I've got an SfPullToRefreshControl. In it's PullableContent I've got some labels displaying actual values. Under this PullToRefresh Control I've got a list of SfCards, which contain an SfChart Control with specified ChartTrackballBehavior and ChartZoomPanBahavior.

In case I trigger a Pull-To-Refresh, the contents of these SfCards and SfCharts will be reloaded as well.

By triggering the refresh, and doing it 2-3x, a NullRefException flies:

"System.NullReferenceException: Object reference not set to an instance of an object.\r\n at Syncfusion.SfChart.XForms.UWP.ChartZoomPanBehaviorHelper.OnPointerExited(PointerRoutedEventArgs e)\r\n at Syncfusion.UI.Xaml.Charts.SfChart.OnPointerExited(PointerRoutedEventArgs e)"


Both Syncfusion.Xamarin.Core and Syncfusion.Xamarin.SfChart have the version 20.2.0.45

This problem occures only under UWP, I was unable to reproduce it under Andoid (with simulator).
