Redmine previously used raster icons in the UI. At that time, column headers of some tables displayed raster icons to indicate ascending or descending sort order. The background-* properties were used to position these icons added by the following CSS.

.icon-sorted-asc { background-image: url(../images/arrow_down.png); }
.icon-sorted-desc { background-image: url(../images/arrow_up.png); }

However, the ascending/descending raster icons were replaced with SVG icons in Redmine 6.0. More recently, support for raster icons was completely removed from application.css in r24029.

As a result, the background-* properties in the a.sort selector no longer have any effect and can be safely removed.
