Cloned trapdoors lose their orientation

Minecraft - Release_967804

 

 

Summary:

Trapdoors that are in an opened state will lose their opened status when cloned to a new spot.

 

 

Impact:
Trapdoors used as decorations on builds that need to be block animated will not land in the correct position, which makes the animation look bad. We're adding a sequence to Monsters of the Deep for UA Part 2, and we have to leave out a very cool block animation and sound because of this bug.

 

Repro Steps:

1. Create a new creative world
2. Give yourself a command block and any trapdoor
3. Place the command block down on the ground. Place any block (I've used quartz for testing) on top of the command block. Place the trapdoor flat on top of the quartz block. Open the trapdoor.
4. Place this command in the command block: "clone ~ ~2 ~ ~ ~2 ~ ~ ~3 ~"
5. Power the command block

Your setup should look like this:

 

Observed Results:
The trapdoor is cloned into a flat position instead of a vertical position.

Expected Results:
The trapdoor should be cloned into the same vertical position as the original.
