Command Blocks from dispensers are removed the ability to place command blocks.

Command blocks can be placed down by dispensers, and I expected it to do just that.

What actually happened was the dispenser dropping the block as an item, not as an actual block.

How to trigger it:
1. Create an NBT command block
2. Place it in a dispenser
3. Activate it

I have made sure it is not a dropper. Bug or intended?
