[racket] Scribble secref unlinked in PDF output

Hi Matthew,

Perhaps it is related to how figures are moved about during rendering.

I'm attaching an example source file, test.scrbl, and the PDF output after running "scribble --pdf test.scrbl".

When I open the PDF on my system with Preview, the links to figures 1 and 2 take me to the wrong pages.

When I remove the padding text in the source and re-run scribble, the links go to the right place in the resulting PDF.

Kind regards,



Tim
