The row reordering functionality does not work correctly when the draggable column has a small width.
https://dojo.telerik.com/@user192/ipOyacoH
Open the Dojo and try to reorder a row. The icon inside the hint will keep changing and in some cases you won't be able to drop the row to the expected position.
If you move the hint a bit to the right(towards the next column) this behavior disappears.
The reorder hint shimmers and in some cases does not allow for reordering. This occurs when the column width is small(30px in the example).
Reorder should work as expected, regardless of the column width.
