Sorry, I never delved into the lilypond-book-preamble; I always treated
it as a black box.

My first suggestion is to try adding a [papersize=a3] or something like
that.  Obviously you'll have seen that compiling the full .ly (instead
of only the "Start cut-&-pastable section" [shouldn't that be
"pasteable"?] contains

Drawing systems... 
warning: compressing over-full page by 29.5 staff-spaces

so apparently lilypond decides that the page height is less than it
should be?  a git grep in the code reveals that this warning comes from

lily/page-layout-problem.cc
...
/**
   For ragged-last pages, we usually want to stretch the page so that it
   is not much more compressed than the previous page.  Here, if ragged
   is true and you pass a value of fixed_force that !isinf, then I will
   try to space this page using the given force.  If it does not fit, I
   will resort to just filling the page (non-raggedly).
*/
void
Page_layout_problem::solve_rod_spring_problem (bool ragged, Real
fixed_force)


so maybe playing with various [ragged] options would help?

another idea is to try commenting out bits and pieces of
lilypond-book-preamble.ly until you find the problem-causing line(s).
Start by copying that file into a new directory (along with the
snippet), rename the file (and the \include), then comment away.
Standard "making a minimal snippet" thing.

Sorry I couldn't be more help,
