 [40665] introduced an extra space in the `<ul>` tag for submenus:
 {{{
 <ul  class="sub-menu">
 }}}

 This [https://smthemes.com/support/topic/sidebarinsportsmt_menu/ caused a
 regression] in some older themes that specifically look for `<ul class
 ="sub-menu">` to replace it with something else, for example:
 {{{
 function smt_menu($a) {
         $a=preg_replace("/<ul\sclass='children'>/", "<ul
 class='children'$2><div class='transparent'></div><div class='inner'>",
 $a);
         $a=preg_replace('/<ul\sclass="sub-menu">/', "<ul class='sub-
 menu'><div class='transparent'></div><div class='inner'>", $a);
         $a=preg_replace("/<\/ul>/", "</div></ul>", $a);
         return $a;
 }
 }}}
