Puppetmaster Dorian bug with dark gifts?

I just played a game of standard Hearthstone where I had the 5 mana legendary Puppetmaster Dorian on board and played Nightmare Lord Xavius and drew a minion with the “reborn with all enchantments” dark gift on it, yet in my hand I received a plain 1 mana 1/1 copy of it.

Since Dorian “creates a copy that costs 1 mana and has 1/1 stats”, shouldn’t both of the minions drawn with Xavius have the reborn dark gift?

isnt darkgift always battlecry
