The bug

Chests, trapped chests and ender chests that were placed in earlier versions of the game do not make their opening sound when opened unless broken and replaced. Note that items inside still exist after upgrading.

How to reproduce

1. Create a new single player world in an earlier version (tested with both 1.12.2 and 18w05a)
2. Place a chest, trapped chest and ender chest
3. Exit and quit the game
4. Launch version 18w07c and open the same world
5. Opening any of the three chests makes no sound

Note: Chests placed when using 18w07c make the opening sound as normal.

Additional note: I have just discovered that this only happens the first time the world is loaded in the new version. Once it has been saved and reloaded the chests make their sounds as normal.
