Sheen from IBL isn't being affected by AO

[bhouston]

Description

The sheen effect I am noticing isn't being darkened by AO in the case where the Sheen is resulting from the IBL. When sheen is the result of the IBL it is considered to be indirect lighting and as such it should be decreased in areas where the ambient occluding factor is high.

I can not see this being done anywhere in the shader code and I have examples where it is cause very problematic lighting issues.

Reproduction steps

Create an AO 1 area, then light it via indirect. It will be black. Add sheen and it will become white.

Code

I don't have any code examples.

Live example

I do not have one yet.

Screenshots

Such as this internal crease of a sofa, when I increase sheen the AO'ed area becomes white - that is very wrong:
