Hello, what I've noticed is that if you jump/land on the very edge of a slime block (on any side), you won't bounce. Instead, it will have the properties of a normal block. For example, you will take fall damage. This makes it very annoying in maps, and I have died a few times to this.

Duplicates or relates to MC-1133.
The block the player lands on is calculated by the block under the player's center; if the player is more than half off the slime block, it will not work.
