lilypond book preamble not cropping page

[Gilberto Agostinho]

Hello everyone,

I hope you are all well and had a great year. I noticed that since 
version 2.24.x, lilypond-book-preamble has stopped automatically 
cropping the output around the music grobs.

*1) *This is the behaviour of 2.22.2, which is what I expect when using 
lilypond-book-preamble:

```
\version "2.22.2"
\include "lilypond-book-preamble.ly"

{
    c'4 d' e' f'
}
```

*2) *And below is the behaviour introduced sometime after 2.22.2, 
possibly post 2.24.x:

```
\version "2.24.1"
\include "lilypond-book-preamble.ly"

{
    c'4 d' e' f'
}
```

Is this an intended new behaviour of lilypond-book-preamble or is it a 
bug? If the former, is there a way of enabling the old automatic crop?

Best wishes,
Gilberto
