When dropping carrots, potatoes, etc, villagers go out of their bed on the sleeping position

What I expected to happen was...:
The villagers waking up to take the carrots

What actually happened was...:
Villagers walked on the sleeping position, got out of the beds without changing it. This happens to me only on servers, on singleplayer it seems to work just fine. This has happenned to me on many different servers, many times.

Steps to Reproduce:
1. On a server, make some villagers sleep.
2. Drop some carrots on the ground, near the beds.

3. The villagers will move on the sleeping position, without "waking up"
