Summary:
Encounters can lead to another Encounter instead of leading to a larger chamber as noted in the 24w33a article.

Steps to reproduce:
1. Create a new world with the seed: 504860458143421387
2. Run the following commands in order:

/execute in minecraft:overworld run tp @s 1319.00 92.24 462.50 3.02 7.85
