This issue doesn't appear to be fixed in 1.18 Pre-release 1, therefore, I'm requesting for this ticket to be reopened. You can create a world with the following seed and teleport to the following coordinates in order to reproduce this in 1.18 Pre-release 1.

This issue was present in 1.18 Pre-release 1, but is no longer in 1.18 Pre-release 3 likely due to the fix of MC-223840. There is no need to reopen this report. 🙂
