Access Relationship value from deleted model tombstone in SwiftData.

I’m developing an app using SwiftData. In my app, I have two models: User and Address. A user can have multiple addresses. I’m trying to use SwiftData History tracking to implement some logic when addresses are deleted. Specifically, I need to determine which user the address belonged to. From the documentation, I understand that you can preserve attributes from deleted models in a tombstone object using @Attribute(.preserveValueOnDeletion). However, this isn’t working when I try to apply this to a relationship value. Below is a simplified example of my attempts so far. I suspect that simply adding @Attribute(.preserveValueOnDeletion) to a relationship isn’t feasible. If that’s indeed the case, what would be the recommended approach to identify the user associated with an address after it has been deleted? Thank you.

@Model class User {
  var name: String
  @Relationship(deleteRule: .cascade, inverse: \Address.user) var addresses: [Address] = []
  
  init(name: String) {
    self.name = name
  }
}


@Model class Address {
  var adress1: String
  var address2: String
  var city: String
  var zip: String

  @Attribute(.preserveValueOnDeletion)
  var user: User?
  
  init(adress1: String, address2: String, city: String, zip: String) {
    self.adress1 = adress1
    self.address2 = address2
    self.city = city
    self.zip = zip
    self.user = user
  }
}

for transaction in transactions {
  for change in transaction.changes {
    switch change {
      case .delete(let deleted):
        if let deleted = deleted as? any HistoryDelete<Address> {
          if let user = deleted.tombstone[\.user] {
            //this is never executed
          }
        }
        
      default:
        break
    }
  }
}
