MakeOuterQuote seems to be ignored

[DenMesh]

\documentclass{article}

\usepackage{polyglossia}
\setmainlanguage{russian}
\setotherlanguage{english}
\defaultfontfeatures{Ligatures=TeX}

\setmainfont{Liberation Serif}
\setsansfont{Liberation Sans}
\setmonofont{Liberation Mono}

\usepackage{csquotes}
	\MakeOuterQuote{"}

\begin{document}

\enquote{в кавычках}% line 1

"ещё в кавычках"% line 2

\end{document}

Line 1 produces expected results; line 2 outputs two ". If I change the style (ex. using the style option for package) it correctly changes line 1 but still ignores line 2.

Looks like polyglossia is overwriting all of the csquotes settings: it works fine with babel.

Thanks, will pester them instead.
