Hello, Olexandr,

Thank you for the details.

This sounds like an old issue that we had and it is already fixed:

https://github.com/telerik/kendo-ui-core/issues/3582

Please ensure that the latest version of Kendo UI is used.

If the issue still occurs after updating, please provide an example and I will gladly investigate further.

Regards,
Stefan
