#129 Attribute space-before.optimum does not work for footnotes

[Martin Sievers]

The attribute space-before.optimum does not work when used for footnotes, e.g.

Erfolg<fo:footnote place="0">
<fo:inline font-size="70%" baseline-shift="super">1</fo:inline>
<fo:footnote-body>
<fo:block font-size="10.0pt" line-height="1.2" space-before.optimum="1.0cm" color="black">
<fo:inline baseline-shift="baseline">1</fo:inline>
Hinter dem Titel folgen senkrecht zwei kleine Kreuz- oder Sternmarkierungen.
</fo:block>
</fo:footnote-body>
</fo:footnote>
</fo:block>
