I'm trying to catch up with Texinfo mail.

I saw the problem with the Top node not being present in the links you sent above.

There appears to be code to check a CASE_INSENSITIVE_FILENAMES configuration

building your manuals with texi2any -c CASE_INSENSITIVE_FILENAMES=1 and see
if that makes a difference?
