In the sort dialog, the "Sorting preserves formats" checkbox determines whether background colours move with content or not. (See the tooltip for the checkbox for an explanation.)
With regard to the sort buttons on the toolbar, this is determined by the option of the same name in edit->preferences->tools->sorting. The SORT spreadsheet function acts on contents only (and never affects formatting in any way.) This is not a bug.
