When you break a minecart, upon breaking it, it will name itself: "entity.MinecartRideable.name"
What I expected to happen was...:
Upon breaking a minecart, it should not change its name.
What actually happened was...:
It named itself something else.
Steps to Reproduce:
1. Place a minecart on any rail in survival mode
2. Break the cart to drop itself.
3. Its name is now "entity.MinecartRideable.name"
Still happens in 1.10.2, I even took a photo before finding it was already reported.
