The bug I was talking was when setting tagMode of kendoMultiSelect to single, clicking the clear button (x at right of textbox) doesn’t trigger “deselect” event. Not sure if it’s by design. They fixed a similar bug regarding “change” event - https://github.com/telerik/kendo-ui-core/issues/4649.
Repro snippet could be found at
Result: The items that were selected, then un-selected still show as selected in the list
This can be reproduced on the latest demo page. https://demos.telerik.com/kendo-ui/multiselect/index
