Shulkers are tilted

Shulkers spawn and sit at an incorrect, tilted angle instead of aligning perfectly parallel to the block grid.

Stops to reproduce the issue

1. Load a world in Minecraft Bedrock edition.

2. Locate naturally spawning shulkers or spawn a new shulker using a spawn egg.

3. Observe the alignment and model rotation of the shulker relative to the block faces.

Expected result
The shulker should align perfectly straight and parallel to the block grid layout.

Actual result
The shulker is visually tilted and misaligned with the block surface.
