Backbone.Collection bug?

gistfile1.js

_prepareModel: function(model, options) {
  if (!(model instanceof Backbone.Model)) {
    var attrs = model;


    // Bug? Do we forget to pass in options here?
    model = new this.model(attrs, {collection: this});

    // Proposed Fix:
    //model = new this.model(attrs, _.extend(options, {collection: this}));


    if (model.validate && !model._performValidation(attrs, options)) model = false;
  } else if (!model.collection) {
    model.collection = this;
  }
  return model;
},


model = new this.model(attrs, _.extend(options, {collection: this}));
