Some blocks don't randomly rotate correctly

Some blocks don't randomly rotate correctly. The current problems that still happen might be intentional.

Here is a list of cases where blocks don't rotate correctly:

Likely intended:

• Side of dirt, sand, red sand, and concrete powder don't rotate like the side of bedrock, stone, and netherrack

• Coarse dirt, gravel, clay, and terracotta don't rotate at all (even though they are closely related to dirt/stone.
  Top of podzol, mycelium, and grass path don't rotate like the top of grass

Not likely intended:
Bottom of mycelium, podzol, farmland, and grass path don't rotate like the bottom of dirt and grass (even though they all contain the exact texture of dirt)
Infested stone doesn't rotate at all unlike normal stone (sort of ruining the camoflauge aspect when looking closely or using certain resource packs)
