A Minecart chest sent down a U-shaped rail route with one 'dead' or unpowered powered rail to stop the minecart at that point made it all the way to the other end of the rail line. The unpowered rail was outside of the max render distance.
What I expected to happen was...:
The Minecart moves along the rails until it hits the unpowered powered rail and then stops/brakes.
What actually happened was...:
The unpowered rail was outside of the render distance and the minecart did not stop on it, instead it continued all the way to the end of the rail track, which was back within render distance.
Steps to Reproduce:
1. Create a U-shaped rail track going from the top of block stairs, leading to the bottom and back up the other side of the stairs, using powered rails every other rail to power the minecart chest up either side (depending upon the direction it is going at the time)
2. Remove the power from one of the powered rails on one side of the track, outside of the max render distance from the top of the stairs.
3. Set minecart chest off from the top of the stairs and see if it makes it back up the stairs on the opposite side of the rail track.
