      Non-enumerable properties to a Scoped Thread via an arguments object do not get passed properly and do not appear in the object inside of the ScopedThread function. The following snippet of code illustrates the problem. Ideally none of the asserts would fail, but here only the asserts for property 'c' fail, showing that while 'args.a' and 'args.b' both get passed, 'args.c' does not.
