As the Storage interface does not have OverrideBuiltins (unlike its peer, DOMStringMap) it must allow builtins to win and this includes properties added to the prototype chain. A small test of this is: For: Storage.prototype['customProperty'] = 'prototype-value'; window.sessionStorage['customProperty'] = 'storage-value'; window.sessionStorage['customProperty'] should equal 'prototype-value', but instead equals 'storage-value'. Test case attached.
