Decorated Pot drops itself and rewards repeatedly

A decorated pot in the 3 story trial chamber structure with ladders (main corridor structure), this decorated pot that drops loot dropped itself, and repeatedly is dropping itself while giving loot

Edit: After placing and mining ~20 times, it stopped dropping excess loot, and this was done spam clicking right left in a corner
