Summary:
The side textures of end rods when placed in the world are inconsistent, resulting in constant mismatches with the top texture.

Reproduction:
1. Enter any world.
2. Place end rods on different block faces and observe the side textures.

Result:
End rod side textures are different based on the face the rod is placed on.

Expected Result:
End rod side textures match the top texture and do so for every possible direction the rods can face.
