Is there a way to avoid finalizing Credential? If not, do I need to add an empty
destructor?

Why can't you simply use GarbageCollected<Credential>? I wonder why you need to
use GarbageCollectedFinalized.

It's due to the LocalCredential change made here. I suggest you leave it as
*Finalized, but add a FIXME next to the DOMFormData field to reconsider its use
once that becomes Member<>.
