Soul speed "effect" stays when you levitate/fly off of soul sand or soul soil

The bug

When flying off of soul sand or soul soil with creative mode or elytra, your soul speed "effect" stays and keeps the FOV until you land, resulting in an FOV shift. Same also happens when getting affected with levitation. One way to fix this incredibly annoying bug is to disable the soul speed "effect" when flying in creative mode, using an elytra, or levitating.

To reproduce

1. Be in Creative mode
2. Equip soul speed boots
3. Stand on top of soul sand or soul soil
   → Notice that your FOV increases
4. Fly up into the air
   → The FOV doesn't decrease again
