Quick Look doesn't extend Sandbox to "related items"

The Quick Look plugin "StitchBuddy-QL.qlgenerator" is previewing an (embroidery) design file "angel.pES" which comes with a second file "angel.threads" holding an array of additional information (thread colors). To extend the Sandbox the second file is handled as a "related item" using NSFilePresenter / NSFileCoordinator according to this Apple documentation: developer.apple.com/library/ar…c/uid/TP40011183-CH3-SW22. The code fragment to read the related item is attached as "CodeFrag.m" incl. the customized File Presenter "STBThreadFilePresenter.m".
The Quick Look plugin should be able to read the related item file and reflect it in the upper right corner of the preview as "Janome Garne", like shown in the attachment "qlmanage Preview.png". This works with the main app "StitchBuddy" and with qlmanage in Catalina, and with Quick Look before macOS 10.15.
Kernel is reporting a Quick Look error extending the Sandbox (attachment "Console Error.png"), and the Quick Look preview is acting like the related item could not be read: "Brother Garne" in the upper right corner of the attachment "Quick Look Preview.png".
- Steps to Reproduce:
Copy the attached Quick Look plugin "StitchBuddy-QL.qlgenerator" into ~/Library/QuickLook and preview "angel.pes". Compare the result to "qlmanage -p angel.pes -c com.brother.pes". Or download StitchBuddy for free from the Mac App Store, containing the mentioned plugin and using the same code to read related items.
