Texture shown when the player's head is inside of any command block is the conditional command block texture, not the texture matching the block

When going into a command block that is unconditional, it shows the conditional version instead of the unconditional version. This works for all types of command blocks. also, the inside of the command block always faces up, even if it was placed in a different direction.

 

Steps to reproduce:

• Place a impulse, repeating, and chain command block.
• Make sure they are not conditional.
• teleport yourself into the command blocks.
