Renamed containers don't stack after placing and breaking

The bug

If you rename a container in an anvil, then place and break it, it no longer stacks with other similarly named containers.

How to reproduce

1. Get a stack of chests
2. Rename all of them in an anvil
3. Place one
4. Break it

Expected behavior
It keeps its name, so it should stack with the other ones

Observed behavior
The name is kept, but it still won't stack
