Comment (by TobiasBg):

 Indeed, looks like actually setting the object properties has to be done
 ourselves with `__unserialize`.

 See e.g.
 [https://www.php.net/manual/en/language.oop5.magic.php#object.unserialize
 this PHP docs example] for `__unserialize`, where properties and DP
 connection are restored.
 Contrary,
 [https://www.php.net/manual/en/language.oop5.magic.php#object.wakeup the
 example] for `__wakeup` doesn't restore the properties but only the DB
 connection.
