Debug World Pressure Plate Crash

How to activate:
1 - Be in a Debug world
2 - Trigger the wooden pressure plate with anything
Result: Spawns hundreds of items into the game, which then triggers itself hundreds of times, etc.

This made me need to restart my game to get out of the situation. I recorded it in action too:

Note that I think the items despawned after I restarted and rejoined.
