margin-note exceeds page limit in PDF e.g. Racket guide

[spdegabrielle]

What version of Racket are you using?
8.15

What program did you run?
scribble/manual render to pdf

example showing continuation-mark-set->context running beyond edge of page in pdf viewer

page 226
https://download.racket-lang.org/releases/8.15/pdf-doc/guide.pdf

What should have happened?

I'd expect scribble to wrap keep margin notes within gutter by wrapping @racket[continuation-mark-set->context] on hyphens like exn-message in @interaction block on the same page.(see full page capture below).

Not a big issue as manual is intended to be used via browser, but may be frustrating for e-reader users who use PDF. (I was trying to publish print copy via amazon with permission of author)

continuation-mark-set->context

Line 124

@margin-note{The @racket[continuation-mark-set->context] procedure provides best-effort structured backtrace information.}

Please include any other relevant details

Interaction block

@interaction[
(with-handlers ([exn:fail?
                 (lambda (v)
                   ((error-display-handler) (exn-message v) v))])
  (car 17))

'Gutter' guidance from amazon kindle direct publishing:

Insufficient gutter. Books with 407 pages require at least 0.625" (15.875mm) for the gutter (inside margin) and at least 0.25" (6.35mm) for the outside, top and bottom margins.

this may be a starting point

% The \refpara command corresponds to `margin-note'. The
% refcolumn and refcontent environments also wrap the note,
% because they simplify the CSS side.
