Resolution: Works As Intended

Cracking animation just got "fixed" for Chests (normal, trapped and Ender) and signs.
Although it's show (at least in my opinion) incorrectly.
I don't say it doesn't look good!
But with all other blocks in Minecraft the animation starts in the center of that block.
While thees blocks don't.
