Non relatedlinks autocomplete fields are filled with value "undefined" after selecting from autocomplete popup

Relatedlinks modul overrides Drupal.jsAC.prototype.hidePopup function from misc/autocomplete.js.
Overriden function sets input fields value to this.selected.autocompleteValue (line 227), but
this variable is defined only for relatedlinks input fields, so other autocomplate input
fields are filled with value "undefined".

Possible fix:
sites/all/modules/relatedlinks/relatedlinks.js ( replace line 227 with: )

      if(this.selected.autocompleteValue){ // value for relatedlinks input fields
        this.input.value = this.selected.autocompleteValue; 
      }
      else{  // standard value from autocomplate.js for other autocomplete input fields
        this.input.value = $(this.selected).data('autocompleteValue'); 
      }
