StructuredDeserialize expects the first argument to be a record containing the [[Type]] slot, as would be returned by StructuredSerialize and StructuredSerializeForStorage. StructuredSerializeWithTransfer returns instead a record with [[Serialized]] and [[TransferDataHolders]] slots, which must be deserialized using the StructuredDeserializeWithTransfer operation.

It seems like this was an oversight in #3414.

`StructuredSerialize` and `StructuredSerializeForStorage`.
`StructuredSerializeWithTransfer` returns instead a record with
