scrollspy problem with two navs

Created by: devniel

Hi, it seems that scrollspy goes crazy with two navs targeting same elements, I have this approach because of responsive design, one navigation menu is hidden in certain dimensions.

Demo : http://jsbin.com/xowuw/1/

By now, my workaround is a simple filter in scrollspy.js' refresh method :

       var exists = false;

        for(var i in self.targets){
          console.log(self.targets[i], " == ", this[1]);

          if(self.targets[i] == this[1]){
            exists = true;
            break;
          }
        }

        if(!exists){
          self.offsets.push(this[0])
          self.targets.push(this[1])
        }

Thanks !
