In Java Edition, walking on soul sand with soul speed drastically changes the player's field of view, but this is not the case for Bedrock Edition.

How to recreate:

1. Place down some soul sand
2. Get some boots (any type) and enchant them with soul speed (level 3 gives most drastic results)
3. Set your FOV to 110 (Quake Pro)
4. Walk on the soul sand and notice the results

In Java, this gives you a massive headache and makes it very hard to navigate around, but doesn't do anything the FOV on Bedrock. Hopefully, the FOV change for Soul Speed in Java Edition will be completely removed.
