Original issue's description:
> Disallow passing a SharedArrayBuffer in the transfer list.
>
> This behavior changed recently. SharedArrayBuffers should not be put in the
> transfer list, because they are not detached, and that is the meaning of being
> in the transfer list.
>
> This is the V8 side of the change, the Blink side will come next.
