When we call setSorting on the grid's setup, sort icons are not applied to the first sorted column. Currently the only way to show the icon is by manually click (or using jQuery). We should fix this to apply the icons after calling setSorting.
I'm not sure I understand the problem. Calling setSorting immediately after instantiating the grid appears to add an icon to the column header as expected. Perhaps I'm missing some steps to reproduce the issue?
