So after about an hour, my knowledge in electronics, and a joycon repair kit, I have made some discoveries. I do not get the drift with the battery in normal configuration and the vibration box connected. Now it may not be the vibration box, or it could be a combination of both the vibe box and the battery, but I have successfully forced it to drift and stopped it from drifting. My theory is Electromagnetic Interference or EMI. The battery being so close to the joystick is the problem, along with what I suspect, is a latent catastrophic failure (or simply put a damaged run on the board due to normal production of the circuit card itself). The battery lines are acting as an antenna, sending a signal that is being picked up by the small area that is exposed or damaged. While it gets stuck in one direction, as soon as you tap the joystick the opposite way, the signal is cancelled out and stays at rest. The exposed area is acting as a hold switch in a sense, essentially keeping the circuit energized.
