Uncaught TypeError: undefined is not a function

Drag and drop is broken as of 14 hours ago. Here's the traceback from the core-drag-drop from http://www.polymer-project.org/components/core-drag-drop/demo.html and http://www.polymer-project.org/tools/designer:

Uncaught TypeError: undefined is not a function core-drag-drop.html:58

And points to this block of code:

attached: function() {
    var listen = function(event, handler) {
        PolymerGestures.addGesture(this.parentNode, event, this[handler].bind(this));
  }.bind(this);
