Chunks loading very slow since Minecraft 1.19.60.25 Preview

This issue is not a duplicate of MCPE-162424.

Chunks are loading very strangely since Minecraft 1.19.60.25 Preview, it seems that some chunks are too lazy to load and only a few chunks loaded when player is near form them.

The change about chunk generating in 1.19.60.25 might caused this issue.

Steps to reproduce:

Use elytra to fly around the world and pay attention to the chunk loading speed.

Observed results:

chunk loanding speed is much slower compared with Minecraft 1.19.51.
