When I select time slot and then I will go to scheduler calendar, everything is ok. But then when I select one day earlier and open scheduler calendar it's showing previous date. It's reproduceable in latest version https://demos.telerik.com/kendo-ui/scheduler/index (https://dojo.telerik.com/EcalidON) with an option (selectable: true)

Green circle shows it works correctly.

Red circle shows it doesn't work correctly.

I observed it happens when I click one day before previous selection.
