Could you provide an example?

It's a known issue that the current SVG backend does
not embed fonts in the output files, leading to rendering
discrepancies; however, I find differing numbers of pages
surprising, and that might hide another bug.

You may want to try out experimental binaries using the
Cairo backend:

https://lists.gnu.org/archive/html/lilypond-devel/2021-07/msg00070.html

With these, the fonts are embedded. You need to run lilypond
with --svg -dbackend=cairo. These binaries come with all
the warnings related to experimental code.

Best,
