Fix Version/s: Minecraft 19w13b
Java Version 8 Update 191 (build 1.8.0_191-b12)
A redstone signal can pass through a piston like how it would be if you powered a block by repeater / redstone torch, but only when the piston is retracting.
This is similar to the bug reported here, except the examples shown there no longer work in 19w02a.
Except I found cases where the bug still works, as shown in the video below.
What I expected to happen was...:
Redstone signal should not have passed through the piston
What actually happened was...:
I could retrieve a redstone signal output from the piston, but only during the piston's retraction.
Steps to Reproduce:
Video shows examples and easy redstone contraptions to reproduce bug.
