<pre>In order to be safe from information leakage we should make the CustomGetterSetter functions require that the |this| object and the argument (in the case of setters) be from that same origin as the getter/setter function itself.
This is simply a guaranteed hardening against leakage, and as we haven't historically exposed this kind of information it can't be a regression.</pre>
