SoftProof adjustment converts spot colour

[Joachim_L]

1. Create CMYK document. 

2. One layer with an element having a spot colour. 

3. Place on top of the Layers panel a SoftProof adjustment. 

4. Export as PDF with preserving spot colours. 

Result: Spot colour is converted. 

At least I would hope for a Preflight warning, that SoftProof is enabled before export or if easier automatically discarding this adjustment.

I moved this to feature request as it's not a bug. The soft-roof adjustment, at the end of the day, it's still an adjustment, and will be treated like one during export.
