I don't really think that this is a bug, but its a huge annoyance(for me, I don't know for others)
When making a traditional cactus farm* sometimes the cactus item drop can fly into the bottom cactus block and it will get deleted. Not always happening, but it needs more space between farm rows and also having complex systems with redstone so it could work 100% catch chance.
*What I expected to happen was...:
The cactus item drop to get pushed of the cactus block at one random side.
*What actually happened was...:
The cactus item drop got "deleted" by the bottom stem.
Steps to Reproduce:
1. Make a traditional cactus farm*
2. Wait for the cactus to grow
3. Start facedesking of agony.
NOTE TO THE CACTUS FARM: It doesn't only restricted to happen in the Flatlands, and it may be built in other ways.The block above can be any block(even transperant)
