First off, this is the best place I found to post this in, it's not MVC specific, I know.
There seems to be a slight bug in the Gantt chart when using Internet Explorer (I tried Firefox and Chrome, they didn't exhibit this behaviour). Atleast the MVC and jQuery UI versions seem to be affected. You can reproduce this by browsing to https://demos.telerik.com/aspnet-mvc/gantt or https://demos.telerik.com/kendo-ui/gantt/index with IE11 and then scrolling the Gantt chart to the bottom. If you click on any task in the right above "Integration testing", the left side of the Gantt (with ID, Title, Start Time, End Time) will properly scroll to the selected task. But if you click on "Integration testing" or a task below it, the left side will jump to the top, showing "ID 7 Software validation" and you have to nudge your scroll wheel for the left side to focus on the task you clicked on.
This happens on fully updated Windows 7 and IE11 with the version info in the attached picture.
