With this code:

\version "2.23.12"
\include "lilypond-book-preamble.ly"
{ c' }


Compiling the file as

lilypond --svg file.ly

I get cropped SVG output.

What you are describing used to be a limitation of 
lilypond-book-preamble.ly,
but no longer is. It got waived at some point in Han-Wen's heavy backend
refactorings (removing the eps backend among others). Well, it's true that
the primary motivation for these refactorings was better Cairo support.

So the limitation is gone now, even without Cairo. That being said, for the
other reasons I mentioned earlier, it is still a very good idea to use Cairo
for SVG output.

Best,
