After upgrading from 7.x.2.2 to 7.x.2.4 the ascending/descending icons are no longer rendered along with the sort links (price, latest and title) after pressing one of the sort links. I noticed that these icons do show up correctly if I assign the search sort block to the content region. When I assign the search sort block to another region than the content region (e.g. Search Breadcrumb region), the sort icons are disappearing after pressing a sort link. I would like to have the sort links with icons in a dedicated region. Having them in the content region causes some layout issues.
