Regression in latest datomic when transacting data & schema in one tx

Question

Let's say you have a transaction like:

{:db/id :admin/id,
 :db/unique :db.unique/identity
 :db.install/_attribute :db.part/db}
{:db/id "admin"
  :db/ident :admin/bug
  :admin/id admin-id}

(So both schema & data in one tx)

Normally you would expect idents to work properly - e.g. after that transaction (d/entity db [:admin/id admin-id]) would return the :admin/bug entity. Unfortunately that's not the case (though it used to work in previous versions of datomic) - it returns nil. Splitting the transaction into two makes everything work.

Here's a full repro:

(require '[datomic.api :as d])
(def conn (d/connect (doto (str "datomic:mem://" (d/squuid)) (d/create-database))))
@(d/transact conn [{:db/id "new"
                    :db/ident :admin/id,
                    :db/valueType :db.type/uuid,
                    :db/cardinality :db.cardinality/one,
                    :db/doc "Id of the admin"
                    :db.install/_attribute :db.part/db}])

(def admin-id (d/squuid))

@(d/transact conn [{:db/id :admin/id,
                    :db/unique :db.unique/identity
                    :db.install/_attribute :db.part/db}
                   {:db/id "admin"
                    :db/ident :admin/bug
                    :admin/id admin-id}])

(def db (d/db conn))

(if (some? (d/entity db [:admin/id admin-id]))
  (println "All OK - admin is found by identity")
  (println "Admin identity not there? Let's see the entity: " (d/touch (d/entity db :admin/bug))))
