Redstone powered dripleaf duplicates gravity block when unloaded (change dimension, out of simulation distance)

When a dripleaf is powered, it stays up permanently, gravity blocks on dripleaf turn into entities to make it fall. This makes the gravity block switching between an entity and a block, every tick. Then, when unloaded and reloaded, the gravity block is still spazzing out, and an item form of that block is on the ground. This breaks when leaving the world. Mojang: either fix this, or allow anvils to be smelted into nuggets, or ingots
