At a friend's server, I rode a minecart down to his house, and when I got out, the minecart was making its sound when it stood! I destroyed it & it kept playing. I then got out of the server & it still kept playing

1. Create a long minecart ride. Include powered rails. (example: from the spawn to the end)
2. Ride the minecart until to the end.
3. When the minecart stops at the end of the ride, get off, destroy the minecart and quit to the title. The bug has a common chance to occur.
