Description Chris Dumez 2016-09-01 08:57:58 PDT 
Object.preventExtensions() should throw cross-origin:
- https://html.spec.whatwg.org/#windowproxy-preventextensions
- https://html.spec.whatwg.org/#location-preventextensions
- http://www.ecma-international.org/ecma-262/6.0/#sec-object.preventextensions

Firefox and Chrome both throw in the cross-origin case.
