Hi,
If Grid's last column has a long title, trying drag-n-drop to group that last column will get stuck. The mouse cursor's title box is too wide, it overflows to outside of the grid, then the cursor can't be moved anymore.
To reproduce, use this example - https://www.telerik.com/kendo-react-ui/components/grid/grouping, resize the browser to a smaller size so that "Category Name" column title fill up the entire column width. Then try to drag "Category Name" column.
Please see the attached screenshot too.
Thanks,
Jie
