When a player walks away from a minecart that is moving 24/7 the minecart stops moving like if it was paused some how but when the player returns back then it begins to move.

Expected Result:
The minecart will continue to move no matter where you are.

Actual Result:
The players minecart will stop when he or she walks away and will began to move when walking towards it.

How to reproduce:

1. Go on creative mode and get these things, a minecart rail, redstone torch, powered rail, detector rail, piston, redstone dust, and a repeater.
2. Make a circle out of the tracks only use the normal rails for turning and power rail for moving forward, when you make it destroy one powered rail and put a detector rail.
3. After that make a long redstone line with repeaters about 63 blocks and on the 63th block put the piston and turn on the redstone signal from the beginning to make sure it works then turn it off.
4. Now place a minecart and give it a push, after giving it a push walk to the piston block and pay attention to the minecart and remember where it last was before it goes out of site while walking back, when you get to the piston you will see that it is not getting powered so means the minecart has stopped some how, now walk back to the track and you will see it move where you last saw it.

What this bug affects is making a 24/7 moving subway system or any redstone contraption that uses this system.
