This is actually caused by generic.movement_speed being over a certain value, and is not specific to potion effects nor enchantments (MC-197091); they just modify said attribute.
Using /attribute, you can cause this too.
This can be fixed by clamping the FOV within a certain range, while not clamping the movement speed; Or by modifying how the world gets rendered on a wide screen to fix this (also fixing MC-8684).
I think limiting FOV is a good idea regardless, but asymptotically, not with a hard cutoff point. And MC-8684 shows that also properly fixing the actual rendering issue would be good anyway.
