System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 471.68

Blender Version
Broken: version: 3.0.0 Alpha, branch: cycles-x, commit date: 2021-09-14 15:01, hash: 58ab616d4c
Worked: (newest version of Blender that worked as expected)

Short description of error
While doing a fake caustics test with the Light Path Node and the Transparent Shader, I found an issue where the Bump node isn't calculated in the shadows. It’s totally redoable.
Image of Reference to compare 2.93.1 and the 3.00a Cycles X version

Exact steps for others to reproduce the error
To reproduce the issue you just need to create a fake shader using Bump node and a transparent shader.(As in the .blend file sent)

Based on the blend file: Bump node test.blend

We currently do not accept bug reports for the Cycles-X branch of Blender on the bug tracker. Hence I will archive this report.

CC @brecht @Sergey @leesonw if you want to take a look at this.
