In the window.js file, there's a few classes that have a defaultOptions static field. This field is used inappropriately, for example:

Control.Modal = Class.create(Control.Window,{
	initialize: function($super,container,options){
		Control.Modal.InstanceMethods.beforeInitialize.bind(this)();
		$super(container,Object.extend(Control.Modal.defaultOptions,options || {}));
	}
});

The method extend will mutate the first argument, which is a shared static field. The defaultOptions need to be cloned before they can be extended:

Control.Modal = Class.create(Control.Window,{
	initialize: function($super,container,options){
		Control.Modal.InstanceMethods.beforeInitialize.bind(this)();
		$super(container,Object.extend(Object.clone(Control.Modal.defaultOptions),options || {}));
	}
});
