Torch placed on a cocoa

^{Update by [Mojang] Mega_Spud (Jay Wells):}
Summary:
Torches and other blocks can be placed on cocoa, as if the cocoa has a full block.

Steps to Reproduce:

1. Place a torch onto the side of a cocoa pod

Observed Results:
The torch 'attaches' to the cocoa pod, but is visually hanging upon nothing as the cocoa doesn't occupy the space of a full block.

Expected Results:
Nothing should be able to be attached to cocoa pods (apart from the jungle log that it is attached to)

Screenshots/Videos attached: Yes

Notes:

---

Original Description:
I placed a torch on a cocao randomly, and the torch placed itself in mid air like it was placed against a block.
