If you break a powered piston on his extending part, you will get a piston back

Its a creative mode inconsistency. If you break the piston by hitting the piston body, you get no drop. If you break it by hitting the extended part, you get a drop.

Indeed it does include the mode in the upper summary, but it's best to list all the details, as well as gamemode, in the description.
i already did a comment on a similar problem using doors it has now been fixed so no need to repost
Just read what Jon commented!
So?
Doesn't the whole piston break?
What do you think should happen?
