// happens, but doing so would require calling JS_ClearScope from random

// The compromise is the UXPCObject. When resolving a property on a XOW as
// same-origin because of UniversalXPConnect, we actually resolve it on the

// engine to do all of its work on another object, not polluting the main
// object. However, if the get results in calling a setter, the engine still
// uses the regular object as 'this', ensuring that the UXPCObject doesn't
