let's have a dedicated method to reset height?

       this._list.replaceAllItems(completions);
 
       var highestPriorityItem = -1;
       if (selectHighestPriority) {
         var highestPriority = -Infinity;

           if (highestPriority < priority) {
             highestPriority = priority;
             highestPriorityItem = i;
