Biome particles instantly disappear once the player travels too far

Steps to reproduce:

1. Create a world with seed -1592638483
2. Run /execute in nether run tp @s -439 77 200

Observed result:
The biome particles have an increased despawn rate the further the player travels, yet instantly disappear once the player travels too far.

Expected result:
The biome particles do not generate that far outside of the biome, but do not disappear when the player leaves completely, like in Java Edition.
