Still checking...
At the moment I have
GPL Ghostscript 10.04.0 (2024-09-18)
build from source with
make debug
I run the test with
gs -dPDFDEBUG -dPDFSTOPONERROR -dNOPAUSE -sDEVICE=pdfwrite
-sOutputFile=z.pdf notation-test.pdf -c quit &>out

Indeed , in out I can see

As you said, we can use
mutool clean -d notation.pdf notation.uncompressed.pdf
and I also add mine
qpdf -qdf notation.pdf notation.qdf
(and in theory we can use verapdf, but it validates only pdfa files as far
as I know).
The key point is that with qpdf one can edit the *qdf* file (i.e
notation.qdf in our case)
and call fix-qdf notation.qdf > notation-edited.pdf
to have a pdf.
