Broken: version: 3.0.0 Beta, branch: master, commit date: 2021-11-05 22:17, hash: `rB7a5b8cb20284`
Worked: 2.93.5
**Short description of error**
The Principled Volume node's Absorption Color input produces different results in 3.0.
Found it out after loading my recent project with a bit unconventional volume setup in 3.0, couldn't find a way to achieve the same look as in 2.93.
**Exact steps for others to reproduce the error**
See images and .blend.
