Most of the WebIDL objects for the current editor's draft of Web Authentication are annotated as [SameObject], which won't affect interop based on WD-05 [1]. We should go ahead and annotate ours that way.

Does the implementation actually return the same object all the time? For example, PublicKeyCredential.rawId seems to end up in CryptoBuffer::ToUint8Array, which returns a new object every time it's called. Maybe I'm missing something, where do we ensure that the same object is returned?

I was assuming [SameObject] instructed the object to be cached at the JS-layer, but digging into it, I see it does not. I'm opening a follow-on that I'll tackle ASAP to make sure these are cached objects.

Thanks, :peterv.
