why not do the same as matchesWithAncestors:
var elem = target;
do {
  if (elem.matches(selectors)) return elem;
  elem = elem.parent;
} while(elem != null);

Same difference. Done.

       if (target.matches(_selector)) {
         matchedTarget = target;
       }
       target = target.parent;
     }
     return matchedTarget;
   }
