Z-fighting clouds and blocks

Summary:
This report applies to MCPE-36855 but does not duplicate it!

In version 1.16.220.50 (and in some of 1.19), z-fighting of clouds and full blocks have been fixed. But z-fighting still occur with some blocks.
Blocks that trigger z-fighting (I kind of double-checked everything):

• Big Dripleaf (curved tip only)
• Leaves
• Scaffolding
• Monster Spawner
• Sculk Sensor
• Stonecutter
• Anvil

---

Steps to reproduce:

1. Build up to cloud level.
2. Wait for the edge of the cloud.
3. Place the block on the edge of the cloud.

Observed results:

Z-fighting occur between clouds and placed blocks.

Expected results:

There shouldn't be a z-fighting.
