Bees get stuck on stalagmites.

Bees will not fly around stalagmites. Bees colliding with stalagmites will continuously try to fly through them. Once they are stuck, their flying animation stops. Observed in a vanilla minecraft realm.
What I expected to happen was...:
Bees not to get stuck on blocks.

What actually happened was...:
Bees collide with stalagmites and will not move around them. Their flying animation stops when stuck.

Steps to Reproduce:
1. place 2 block tall stalagmites in areas where bees roam and might collide with them.
