Confirmed in 1.16.1
Confirmed for 1.9 Full realese
This bug was affected minecraft version 1.0.0 or older.
Not only stone, It could be any blocks.
It said on the fix version, 15w31b, still not fixed. :<
Incorrect, Piston arms don't let go pass through when facing directions with the exception of facing west. Which means only Facing West will let player go through.
Yeah, It happened to my survival world when I was farming Rabbit and escaped from fence and I killed escaped rabbits and once I knew this issue was repeating. On history, minecraft 1.6.2 There was "Fixed animals escaping their pens", I made the fence more thicker to prevent this :<. Thanks for reporting for me. : ]
Floating sand can't be done using /setblock command. and only can be done using this method. Weird. :[

I know there is on issue links right next top to the Activity->Comments. Which leads you to same page.
OOPS. Me stupid. :< and I will remove this issue.
They added this recipe since 13w16a [Minecraft 1.6.1] recipe with material J shaped and a wool But removed recipe since 13w18a [Minecraft 1.6.1] Making them non-renewable.
They Removed Enchanted Golden apple since 15w44a. Making this Not renewable.:< But they're found in dungeon chests.
I think This had changed from Minecraft 1.8 that now creepers no longer floats.
I don't think that follows from this bug. This bug happens when two pistons rapidly extend, even if there's no ceiling obstructing them.
