Describe the issue (IMPORTANT)

Bounciness from beds or slime blocks can be "stored" if you land on them but don't touch the block at first. Then touching the block's top surface at any point thereafter, which the player will be launched up at the distance they would have from falling that height.

Additional Context (OPTIONAL)

https://github.com/Roadhog360/Et-Futurum-Requiem/blob/master/src/main/java/ganymedes01/etfuturum/blocks/BlockSlime.java
onFallenUpon and onEntityCollidedWithBlock seem to assume they will immediately run after the other, even though you can fall on a block without actually touching it.
