--- Comment #3 from Travis Leithead [MSFT] <travil@microsoft.com> ---
Is this behavior for [[DefineOwnProperty]], now basically the same as if the
named properties object were considered non-extensible? e.g., it seems weird to
get this behavior, yet Object.isExtensible() would still say true? If we
changed this to simply mark the option (internally) as preventExtensions()
would that do the trick?

Of course, it's weird to have own properties magically come and go too, so I'm
not sure what's more or less consistent here...?
