Bug of using Magister Dawngrasp's hero power

It actually seems to be getting worse. Prior to today I’ve been able to reconnect to the game and continue playing after my opponent used Dawngrasp’s hero power. Today, I reconnected as soon as I saw it happening, and it just gave me a loss instead of letting me play out the game. There was 0 chance my opponent actually was able to kill me. The program just gave up and gave me a loss. This was in a paid Duels run, too, so I’m extra pissed about it.
