J.C. Jones b3996e4339 Bug 1384623 - WebAuthn [SameObject] attributes must cache those objects r=qdot
Peter points out [1] that I made assumptions that [SameObject] would handle
caching at the JS-layer, but it does not. This bug is to cache those objects [2]
on the heap, and add tests that they are indeed the same.
