    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
