What's interesting is that my locally compiled web.pdf (with Xetex
version 2017.03.30:1237) displays page 10 almost correctly, in that
the page stays A4 vertical but the image is rotated 90°
counter-clockwise. See attached the extracted page.
web.pdf on lilypond.org was built with a more recent version of
Xetex.
I think that it is not caused by the difference in XeTeX version.
Does your environment have `extractpdfmark`?
No, it's not packaged for Fedora.
Should I install it from source?
https://github.com/trueroad/extractpdfmark
GUB has `extractpdfmark` and Ghostscript 9.20.
In such environments, PDFs are processed by Ghostscript after
extractpdfmark.
At that time, Ghostscript seems to rotate by "majority decision".

`-dAutoRotatePages=/None` option for Ghostscript seems to need.
This will prevent landscape pages like lilypond.org web.pdf page 10.
However, it can not prevent image rotation like your web.pdf page 10.
