Setup: Place sticky piston with slime-block, a other sticky piston and a other slime block in-front(See attachment 1. Start.png).

Recreate:
Power the first sticky piston (See attachment 2. Powered.png). When Unpowering the first sticky piston, the expected result should be that the piston will pull-back all blocks connected trough slime-blocks (3. Expected.png) but the thing that is happening is (3. Result.png).

Which Isn't logical, Why is a block pulled back by a slime block, but can a slime block that is connected to a block not be pulled back by the block? Cause that same slime block is still sticky towards the block, (I Hope this is explained clearly, English is not my first language).
