Biblatex (footcite) 和 microtype

Question

Biblatex 的配置是，所有作者姓名都以小写字母书写，并且 microtype 设置为调整小写字母之间的间距。

\SetTracking{ encoding = *, shape = sc }{ 45 } 

这对于文档和参考书目来说效果很好，可惜它对脚注不起作用。有没有办法将此间距也应用于脚注？

我尝试的是

\SetTracking[ context = footcite]{ encoding = *, shape = sc }{ 45 }
\SetTracking[ context = footnote]{ encoding = *, shape = sc }{ 45 }

但没有效果。
