Blocks in Sulfur Cubes do not face the same way as they do when placed in the world

This notably happens to all blocks - carved pumpkins are easiest to see this with.

Observed behavior:

The Sulfur Cube is facing north and the placed Carved Pumpkin is facing north. The Carved Pumpkin within the Sulfur Cube is not facing north.

Expected behavior:

The Carved Pumpkin in the Sulfur Cube should also be facing north.
