Well, all the main developers of lyluatex are on the LilyPond lists, so
you have come to the right place ;-)

I don't have the opportunity to do a full test right now, but I'm 95%
sure it's about the following issue (which you should fix in the
LilyPond file).

1)
lyluatex uses the *cropped* output created with "lilypond-book-
preamble.ly".

2)
When you combine stencils the way you do LilyPond doesn't automatically
know the "extent" of the combined stencil.

3)
This can lead to the extended stencil being cropped.

3a)
You should be able to replicate this when compiling with LilyPond but
including the line
  \include "lilypond-book-preamble.ly"


I can't test a proper solution but basically somewhere in your stencil
callback you should do a 
  (ly:grob-set-property! grob 'X-extent <some-pair>)

where <some-pair> provides the actual extent of the combined stencil.
This is something the people on this list should be able to help you
with.
