Sorting by displayField setSortByDisplayField broken in grouped ListGrid

Hi Isomorphic,

please see this sample. Sorting by displayField works as you can see when clicking "Item Name".

Now if you group the grid by the "Quantity"-column, sorting by displayField is no longer correct when you click "Item Name". See also attached screenshot.

Tested with online showcase (v10.0p_2015-05-07) and GC42, FF26 and IE11.
