Jumping on Crops causes massive drops, crashes world

A player on a realm accidentally jumps on a potato crop and it created a fountain of potatoes, 1000's and 1000's of potatoes lagging the realm. I was able to recreate the bug on a back-up of the world. I had to jump on multiple crops before it happened, but was able to recreate it twice, potatoes, carrots and wheat seeds. Didn't try other crops.
