There still is some redstone update bug in redstone contraptions

I don't know exactly if this is more general redstone behaviour or maybe still related to the new items causing some update malfunctions so sorry if this is not correct

-----------

So I've been testing some redstone contraptions like flip flops and started playing around with pistons and redstone blocks until I got to this:yellow_star: setup.

:yellow_star: = setup.jpg - activate the leftmost piston with a button

What I expected to happen:
The pistons would extend one after another and pull back the blocks afterwards

What actually happened:
The first piston eventually pulled his block back and messed up the entire contraption. To reset the pistons they have to be replaced or recieve a redstone update manually.
