Should the line Z_encoder_decoder = layer_norm(Z_encoder_decoder + Z) in Decoder step 7 instead be Z_encoder_decoder = layer_norm(Z_encoder_decoder +

Should the line Z_encoder_decoder = layer_norm(Z_encoder_decoder + Z) in Decoder step 7 instead be Z_encoder_decoder = layer_norm(Z_encoder_decoder + Z_self_attention) ? Also, is layer_norm missing in Decoder step 8...
