1. Rename a container (e.g. Chest, Furnace, etc.) with an Anvil.
2. Place the container anywhere in the world. Upon opening it, you'll see that the block still retains its name, even when placed.
3. Break the container.
4. The container's name has now disappeared, reverting back to its original name.
I've used the search bar and found no other issue that presented the same problem. I apologize in advance if this is in fact a duplicate of another issue.
