Should a Freezing Trap return a stolen minion to my hand?

I had a Freezing Trap in play and my opponent stole a minion (Scavenging Hyena) from me with Mind Control.

He attacked me with the stolen minion and the minion was returned to my opponent's hand. I expected the minion to be returned to my hand, because I thought that I'm the owner of the minion (that would match the rules of Magic the Gathering).

So my question is now, what is an owner in Hearthstone? Is it similar to MTG? Is this a bug in heartstone?

The description for Sap explicitly states that the minion gets returned to my opponent's hand, while Freezing Trap says it is returned to the owner's hand.

Freezing Trap: When an enemy minion attacks, return it to its owner's hand and it costs (2) more

Mind Control: Take control of an enemy minion

Sap: Return an enemy minion to your opponent's hand

Ownership is transferred when a minion is mind controlled. Ownership in Hearthstone is based upon whoever holds the minion on their side of the board. As soon as a minion is on the opponent’s board, they own it. In this instance the priest you fought had the hyena return to his hand with an increase mana cost of +2 to the card’s actual mana cost because of the freezing trap.

Depending on the situation this is a risky but clever play in order to trigger your trap so that his already in play minions are not returned/sniped with an added bonus of taking away a minion of yours.

Even in instances where mind control is temporary; whoever holds the card is the owner on that specific turn. Example: A priest obtains cards from a rogue using their class special cards and gets a Shadowstep. He uses the minion/card that only temporarily mind controls a minion and uses Shadowstep. The card would return the minion to his hand and not the “original owner” because the priest is the current owner at the time.
