this._size is undefined error

[Kevin F]

I'm forced to upgrade jQuery to 3.4.1 because of security implications, and now I get an error working with a bubble layer.  Using jQuery 1.12.4 the error does not occur.

KendoUI 2020.1.114 is listed as compatible with 3.4.1.  I am using 2020.1.406 so I just assumed it is compatible.  This is part of a MVC application. 

I've attached the stack trace from the debugger console.  Any help is greatly appreciated since I am forbidden to use any earlier versions of jQuery.

Thanks!

An additional note.  The map is inside a kendoWindow which is not visible when the page first loads.  Attached is the stack trace for when the page first loads.

More notes: 

If I remove the bubble layer the error goes away.  Here is the definition for the bubble layer:

layers.Add()
    .Type(MapLayerType.Bubble)
    .DataSource(d => d
        .Custom()
        .Transport(new
        {
            read = new Kendo.Mvc.ClientHandlerDescriptor() {HandlerName = "getRadiusDataSource"}
        })
    ) // DataSource
    .SymbolHandler("radiusSymbol")
    .LocationField("LatLng")
    .ValueField("Value");

Workaround:

Make the kendoWindow visible at first, then close it immediately.

Hello Kevin,

I tried to replicate the behavior on my end but no error seems to be displayed. Below you will find the sample I used for testing:

Could you please let me know what I am missing?

Hi Georgi - 

Thanks for the reply.  Would bootstrap be causing this issue perhaps?  That's the kendo theme I am using.

Hi Kevin,

I have tested the same with our bootstrap theme but the issue still does not replicate:
