Pistons and blocks that get moved by pistons don't move (or bounce in the case of slime blocks) entities.
Steps to reproduce
1. Place a piston
2. Place an armorstand in front of it.
3. Extend the piston.
4. The armorstand doesn't get moved.
This bug is probably due to the changes that were mentioned in MC-88101 🙂

@Les3awe, I don't see how the picture is relevant. That piston will not be able to move the slime block since it is connected to blocks that cannot be moved.
This issue may be relates to MC-88101
@CubeTheThird seems like you don't know how pistons interact with slime blocks ^^
it won't move the obsidian, but it also won't get stuck on it
like on furnaces, chests, etc.
but the armor stand should have been moved to the left
-> the picture shows the piston after it has been moved already -> the armor stand is suddenly inside of the slime block
@Djfe, my comment was for a picture that has since been removed and replaced. I've put a strikethrough on my comment for clarification of this.
