Description of the bug

Copying pages togther with links from one document to another leads to wrong coordinates in the copied document, see reproducer below.

How to reproduce the bug

import pymupdf

document = pymupdf.Document()
document.new_page()
document[0].set_rotation(90)
document[0].insert_link({'kind': 2, 'from': pymupdf.Rect(10, 20, 40, 60), 'uri': 'https://example.org'})

document_copy = pymupdf.Document()
document_copy.insert_pdf(document, links=True)

print('orig:', *(l['from'] for l in document[0].get_links()))
print('copy:', *(l['from'] for l in document_copy[0].get_links()))

prints

orig: Rect(782.0, 10.0, 822.0, 40.0)
copy: Rect(802.0, 782.0, 832.0, 822.0)

    Possible workaround:

    document_copy2 = pymupdf.Document()
document_copy2.insert_pdf(document, links=False)
for i in range(len(document)):
    document_copy2[i].set_rotation(0)
    for link in document[i].get_links():
        link['from'] = link['from'].transform(document[i].derotation_matrix)
        document_copy2[i].insert_link(link)
    document_copy2[i].set_rotation(document[i].rotation)
print('copy2:', *(l['from'] for l in document_copy2[0].get_links()))

    But, it is probably still wrong for scaled or otherwise transformed documents.
