Item frames on the ceiling don't drop items or the frame itself.

What I expected to happen was...:
The item in the item frame (i.e., a map) should have dropped when I punched the item frame with a map in it.

What actually happened was...:
The item disappeared from the item frame, a sound was played indicating that the item had dropped, no item was present on the ground or in my inventory. I tried reloading the game and the missing items still did not appear. This problem is also present when punching the item frame itself. Using silk touch did not remedy the problem. Changing the /gamerule doEntityDrops true did not help.

Steps to Reproduce:
1. place an item frame on the ceiling. (My ceiling was made of smooth stone)
2. place any item into the item frame.
3. punch the item frame.
