I don't know the source of the argument, but Wish Realm has its own history which lays unknown to us.

Wish Realm Robin is whatever age he is due to David's wish and Wish Realm logic. This deals nothing with the Real Robin who did not age during the first Dark Curse for 28 years as noone in FTL or magical realms did.
