Very strange bug that we keep seeing where somehow visualizer is not defined during a prop change.

FYI @jberg I've added some debug stuff to try to decipher what the hell is going on here.

Good call! Let me know if I can help debug if we see something. Guess its the same as the undefined render? Bizarre!
