>+        IDB clients expected transaction operations to be executed in order, but in 
>+        UniqueIDBDatabase::immediateCloseForUserDelete, callbacks in callback map were errored out randomly.
>+        This patch added a callback queue to UniqueIDBDatabase to make sure callbacks will be called in the same order
