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.
