[XeTeX] polyglossia/bidi -- footnote rule alignment

[Kamal Abdali]

I'm using the package polyglossia to typeset documents in Urdu, a
right-to-left language. Polyglossia uses the bidi package whose
documentation implies that the footnote rule is right-aligned when the
footnote is in the middle of some right-to-left text. But the footnote rule
is appearing aligned to the left anyway.

Here is an example:

\documentclass{article}
\usepackage{polyglossia}
\setmainlanguage{urdu}
\newfontfamily\urdufont[Script=Arabic,Scale=1.7]{Lateef}
%\rightfootnoterule   %force footnote rule to right
\begin{document}
افلاطون
\footnote{یونانی فلسفی}
\end{document}


Unless the commented statement is uncommented, the footnote rule shows up on
the left.
