Mankrik + Secret Passage = Hanging animation

Opponent played Secret Passage, drew Mankrik then played him, and the game hung up with card animation over opponents hero.
I recorded it for 5 minutes then gave up.
I had 27 damage on the board with 6 minions, opponent on 8 health… if this is an exploit to prevent lethal then its a bad one - can anyone replicate it?
