Hello, Alan,
Thank you very much for reporting this.
I have moved it to our feedback portal here:
I have also created a GitHub issue if you prefer to monitor it there:
https://github.com/telerik/kendo-ui-core/issues/5623
Finally, as a small gesture of gratitude, I updated your Telerik points.
Kind
Regards,
