Huge bug with Galena Gauntlet / Shulker boxes

[stonezey]

When using a Gauntlet with a tool to mine a Shulker Box, doing so removes all its items and data; i.e. its name and contents are deleted and it is reverted to a default Shulker Box (but maintaining its color). Found this the hard way in survival and I feel as if this bug deserves more attention (I cannot find anything on this)
