Flag "Block right click"

Hi,
when this flag is enabled, there is a javascript error that stops the loading of the web page (see below).

From Javascript Console (Mozilla Firefox Developer) I got this:
SyntaxError: illegal character

Source code:

<p><script type="text/javascript">function fpDisableContextMenu(imgs) {
   function absorbEvent_(event) {
      var e = event || window.event;
      e.preventDefault && e.preventDefault(); // ERROR HERE
      e.stopPropagation && e.stopPropagation();
      e.cancelBubble = true;
      e.returnValue = false;
      return false;
   }
   imgs.on("contextmenu ontouchstart ontouchmove ontouchend ontouchcancel", absorbEvent_);
}
jQueryFJGWPP(document).ready(function(){
   jQueryFJGWPP("#flickrGal0").on('jg.complete', function() {
      jQueryFJGWPP("#flickrGal0").find("> a").swipebox({
