player.setSimulationDistance(1) doesn't work

Expected behavior

player's should be able to have a tick view distance of 1, i.e the chunk they are in and all neighbouring chunks or a tick view distnace of 0, just the chunk they are in,

Observed/Actual behavior

it seems clamped somewhere to be a minimum of 2 chunks. Setting lower than 2 doesn't throw error or anything it just silently fails.

Steps/models to reproduce

player.setSimulationDistance(1) (doesn't work) vs player.setSimulationDistance(2) (works)

Plugin and Datapack List

Just the plugin for testing player.setSimulationDistance()

This is a limitation of how the chunk system works, the lowest possible value for both the simulation-distance and the view-distance is 3 (chunk the player is in + 2). This is also documented in the config docs.
