Description

This new PDFCloneUtility.checkForRecursion function breaks support for a lot of existing PDFs. I've seen a lot of documents where the /Prev and /Next entries point to the parent element. So this breaks support for a lot of existing PDFs which could be processed before. I would suggest to remove these new check.
