If you need more info, just reply.
It's a really cool bug, and it would be great in "train stations", so I honestly hope you leave it 🙂

Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases. If this has been done, we can reopen the issue.
Keep in mind that the "Resolved"-Status on this ticket just means "Answered", and that we are waiting for further information on whether this issue still exists or not. We will reopen it as soon as the requested information has been delivered.
Confirmed, but it really only works in that one scenario, with a block above, and a block in front.
