I'm using Kendo UI R3 2021 SP2 (version 2021.3.1207). There is a bug in the Gantt component (https://github.com/telerik/kendo-ui-core/issues/6547). This bug has been fixed in Kendo UI R1 2022 SP1 (version 2022.1.301), but I cannot upgrade to the new version due to rendering issues. How can I fix the Gantt issue while staying on version 2021.3.1207?
