Slime blocks no longer launch arrows
The bug
It was possible to launch arrows into the air using a slime block and piston. When the piston was activated it would push the slime block up and any arrows on top of the slime block will get launched in the air. In 1.11 this no longer happens.
How to reproduce
- Put down piston that can be activated via lever, button, etc.
- Place slime block on top of the piston
- Take bow and shoot arrows into the top of the slime block
- Activate piston
→ Most arrows stay on the slime block and do not launch up like in previous versions

Don't see a bug here. Launching arrows was never an intended feature.
Is it possible to make it an intended feature?
It is interesting that it was never an intended feature when it is used to build a catapult in the recently published book
"MINECRAFT MEDIEVAL FORTRESS" by MOJANG.
Can confirm for MC 1.12.1.
I also noticed that some of the arrows are glitching in the air when reproducing this bug.
Confirmed for 1.13.1.
Can confirm this was an issue in 1.15.2, however it is fixed in 1.16.1 - arrows are now launched into the air again.
