Retain resized column width after sort.

We have grid where all columns are resizable and sortable. When resizing a sortable column on the mouseup event sort is being invoked. Whenever sort is called the width of the columns are being reset to their initial value. Is it possible to...
1. Prevent the call to sort on the mouseup event from the resize grip
2. Retain a columns width post sort rather than resetting the columns width to its original value.

No files or tests are named. Start by reproducing the resize-grip mouseup behavior and tracing the resize and sort handlers; confirm whether sorting is triggered by the grip event and where column widths are reset. Done means resizing a sortable column no longer invokes sort unexpectedly and its width remains after sorting.
