Bug 104263 – DOM bindings do not work with delete

• Status: NEW
• Component: DOM

[Erik Arvidsson]

For some reason delete does not work to remove properties from the dom wrappers (both JSC and V8)

assert(window.hasOwnProperty('NodeList'));
delete window.NodeList;
assert(!window.hasOwnProperty('NodeList'));

assert(Element.prototype.hasOwnProperty('focus'));
delete Element.prototype.focus;
assert(!Element.prototype.hasOwnProperty('focus'));
