System Information
Operating system: Windows 10
Graphics card: Nvivia Titan XP

Blender Version
Broken: blender-3.6.0-windows-x64, blender-3.5.1-windows-x64
Worked: blender-3.3 LTS

This was a two-step regression:

First, creases broke with a8a454287a
Then, this got partly fixed with 57ea827bfb (but not fully it seems)

Short description of error
In this example when trying to use Solidify modifier in COMPLEX mode to get flat boundary in combination with Subdivision Surface modifier we see that that shape is distorted. But when we go to Edit mode - Vertex view and just slightly move the Vertex Crease slider - the shape becomes correct! Same file in Blender 3.3 LTS looks correct without any actions - just as it is.

Exact steps for others to reproduce the error
Based on the attached .blend file. There is a simple shape with creases on borders and Solidify (in Complex mode) and Subdivision modifiers.

Applying the modifier to both cases, we can see that Edge Crease propagation in Solidify Complex is different from Simple.

This doesn't seem intentional, so I'm confirming it as a regression.

@weasel, would you like to check?
