docbook-xsl 1.68.1 and multiline footnotes

[Mark Derricutt <mark@talios.com>]

Hey all, just updated my XSL stylesheets the other day to 1.68.1 and 
noticed that I'm getting some text bleed when a page has a multiline 
footnote.

The main body text is just printing over the footnote without switching 
to a new page above the footnote.

Does anyone know if this is a bug in the stylesheets that could be fixed 
by adding something to my customisation stylesheet?
