Scheduler Custom Editor works but double-click throws NullReferenceException

[Daniel Glake]

I have created my own event dialog that is shown instead of the standard QuickInfoPopup and Editor of Syncfusion. Therefore I implement the

OnPopupOpen(PopupOpenEventArgs<AppointmentDto> args)

method and set

args.Cancel = true;

then opening my own dialog.

When clicking into a cell or on an event the dialog opens and everything is fine. But when double-clicking into a cell, the following exception occurs (everything else still works, but the exception bothers me):

Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100]
      Unhandled exception rendering component: Object reference not set to an instance of an object.
System.NullReferenceException: Object reference not set to an instance of an object.
   at Syncfusion.Blazor.DropDowns.SfDropDownList`2.d__530[[System.String, System.Private.CoreLib, Version=7.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e],[Syncfusion.Blazor.Schedule.Internal.DropDownFields, Syncfusion.Blazor.Schedule, Version=23.1.43.0, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89]].MoveNext()
   at Microsoft.AspNetCore.Components.RenderTree.Renderer.GetErrorHandledTask(Task taskToHandle, ComponentState owningComponentState)

The same behavior occurs with this Syncfusion-example:

Using the provided code of the example, double-clicking throws the aforementioned exception.
