Is this a regression?

No

Description

Based on your test unit example, if I change the "id" key of the models used to a custom one, and set it up properly, it's not working properly, objects won't be merged.

interface TodoUI {
  uuid: number;
  open: boolean;
}
interface Todo {
  uuid: number;
  name: string;
}

const todosStore = createStore(
  { name: 'todos' },
  withEntities<Todo, 'uuid'>({
    idKey: 'uuid',
  }),
  withUIEntities<TodoUI, 'uuid'>({
    idKey: 'uuid',
  })
);

todosStore.update(
  addEntities({ uuid: 1, name: 'foo' }),
  addEntities({ uuid: 1, open: true }, { ref: UIEntitiesRef })
);

todosStore.pipe(selectEntity(1, { ref: UIEntitiesRef })).subscribe((todo) => {
  console.log(todo);
});

todosStore
  .combine({
    entities: todosStore.pipe(selectAllEntities()),
    UIEntities: todosStore.pipe(selectEntities({ ref: UIEntitiesRef })),
  })
  .pipe(unionEntities())
  .subscribe(console.log);
