[MC-310789] Chunks sometimes don't fade in correctly

Chunks no longer fade in correctly. While testing another bug, I came across an issue where chunks sometimes don’t fade in properly. This affects both OpenGL and Vulkan rendering backends. This issue starts to occur in 26.3 Snapshot 5, likely due to the fix of MC-310041.

Environment

CPU: Intel Pentium Silver N5000 GPU: Intel UHD Graphics 605 OS: Windows 10

I can confirm.
To add extra context this issue seems to be triggered by loading chunks that have already been loaded previously
Ergo:
- Fly in one direction
- Turn around
- The issue will only affect chunks that you did already load in the past
