Actually, the bug was in the DropDownList widget itself. Even though, we have a rich unit and functional test suit run in a CI fashion, sometimes bugs slip out. We are actively developing Kendo UI suite and new features and enhancements are introduced constantly. In this process, malfunctions could be released, which we try to minimize as much as possible.
When we or our users detected a bug, we are trying to fix it right away to minimize the inconvenience. Like in this case, the issue is already addressed and the fix will be available in the next release of Kendo UI due to the end of next week.
