Here is a quote of my answer to the ticket opened on the same subject:
Thank you for contacting us and for providing a solution for the described issue. Unfortunately, even if we incorporate the suggested solution, we still cannot guarantee that Kendo UI will work. We use instaceofacross our code for checks like value instanceof kendo.data.ObservableObject, which will not work in this case. What I can suggest you is to modify the source code of the Kendo UI manually In order to add support for these scenarios. Note that we can not provide support for modified Kendo UI.
I will ask you continue our conversation in only one thread in order to avoid any duplications
