Entering a mobs view in spectator mode does not change if world is changed

What I expected to happen was...:
Entering a mobs view in Spectator mode, leaving a world, and joining a new world, would give me my regular view back.

What actually happened was...:
I created a world to test out Spectator Mode, I entered a creeper's view, left the world and joined a new world. The Creeper's view[Shader], was still there. Yet, I could move around in Survival and creative. I also tested this out with Enderman and Spiders. The result being the same, the mob's respective Spectator View[Shader], was still there.

Notes
Pressing F5 in game fixes the problem

Steps to Reproduce:
1. Create a world
2. Spawn a Creeper, Enderman, or Spider
3. Enter Spectator mode
4. Enter their view
5. leave the world
6. Create a new world/ or join another different world
