Bees get lost in unloaded chunks

While playing with bees and beehives, I noticed that bees tend to disappear over time. Later I went exploring and found my bees sitting nearby in unloaded chunks.

What I expected to happen was...:
Bees to venture out and come back over time

What actually happened was...:
Bees venture out but end up stuck in unloaded chunks

Steps to Reproduce:
1. Have a bee hive or nest with bees
2. Wait for bees to venture far out
3. Search unloaded chunks for flowers to find lost bees
