Tamed rabbits teleport to player after switching to spectator mode

I found some tamed rabbits after starting a new world in 14w33c. Nearby was a village with some carrots. I was able to harvest the carrots and tame some rabbits. They started to follow me around.

Then I switched my game mode to spectator and flew around for a while.

While in spectator mode near some lava the tamed rabbits teleported to me and died in the lava.

Is this expected behavior?
