Teleporting entities into unloaded chunks deletes them from the world in 1.18.30

Partner Rank: 1 (Critical)

Partner Team Reporting: Oreville Studios

Verification builds: 1.18.30.04_rc2

Summary:

Teleporting entities into unloaded chunks no longer works like previously, and the entities are deleted from the world. Once the chunks have been loaded at least once and saved to disk, the bug still occurs with about ~10% of the time.

Impact:

This impacts content live on the store and content in development since we often summon entities and teleport them to specified locations regardless if the chunk is loaded or not. Since most of our content is linear, having entities missing from the world can halt progression of the map and have other negative unintended consequences. This more than likely affects most partner's content in some capacity in addition to our own.

Repro Steps:

1. Create a new world (superflat preferred for testing).
2. Enter world, and run /summon husk ~~~
3. Run /tp @e[c=1, type=husk] -10000 -60 0
4. Run /tp @s -10000 -60 0

Observed Results:

Husk was not teleported to the location and was deleted from the world.

Expected Results:

Husk should be teleported to the location specified in the teleport command.

Regression Builds: 1.18.12

Notes:

As stated before, the bug occurs 100% of the time if the chunk has not been saved to disk at least once, and occurs less often after the chunk has been loaded at least once.
