Description Erik Arvidsson 2012-04-25 16:51:51 PDT 
The descriptor for the constructor WebIDL attributes on Window are broken

Object.getOwnPropertyDescriptor(window, 'HTMLBodyElement')
configurable: true
enumerable: true
value: function HTMLBodyElement() { [native code] }
writable: false

window.HTMLBodyElement = 42;
42

Object.getOwnPropertyDescriptor(window, 'HTMLBodyElement')
configurable: true
enumerable: true
value: 42
writable: true

The Apple port (JSC) correctly returns writable: true
