placing a boat on a moving slimeblock will enable an old boat jumping glitch

I'm reüploading this because it got linked as a duplicated even though the issue is different and the mod won't respond mods name is "OcelotOnesie".

By placing a boat on top of a slime block that is getting moved by a Redstone clock it will launch you high up into the air sometimes when you enter the boat.

Steps to reproduce:
1. Make the machine (Redstone clock connected to a piston with a Slime Block
2. Drop a boat on top of the moving slime block
3. Get into the boat and get launched to the moon
