Using /kill ceases most if not all functional gameplay

In the new snapshot, using /kill in a world will prevent the player from doing anything when they respawn. I've tried making new worlds and the issue only occurs once I use /kill. The player will be automatically put into a pseudo-3rd person mode. The player's head won't follow the camera. The black looking screenshot is actually my game in 1st person. It is viewing my head as if I weren't controlling my own model and were inside it.
