Description Jorj 2025-05-13 16:27:26 UTC 
The function seems to always throw the exception "Cycle detected in outlines" for any PDF that has a table of contents.
Among failing PDFs also is the Adobe PDF specification 2008.

In PyMuPDF, we can only work with the variant pdf_rearrange_page2(doc, list, 0)
which interfaces with the original.

    Bug 708541: Fix cycle detection in pdf_rearrange_pages.

    We were marking/checking an object for cycles in strip_outline,
    but we immediately call strip_outlines with it, which checks
    itself!

    Only check in strip_outlines.

Thanks for such a fast fix!
