Arrow-button triggers the List even if the Text-input is disabled

Using modules that add the attribute "disabled=disabled" at Text-input the Arrow-button should be disabled too. Instead of this, it pop-ups the List and when you select an item from list Text-input is being updated.

So... editing the autocomplete_deluxe.js

I replaced

    parent.mousedown(function() {
      if (parent.hasClass('autocomplete-deluxe-single-open')) { 
        jqObject.autocomplete('close');
      } else {
        jqObject.autocomplete('search', '');
      }
    });

With

    parent.mousedown(function() {
      if (parent.hasClass('autocomplete-deluxe-single-open')) { 
        jqObject.autocomplete('close');
      } else if (parent.children('input.autocomplete-deluxe-form').attr('disabled') == false) {
        jqObject.autocomplete('search', '');
      }
    });
