Broken running head using \setmainfont

[komascript]

With LuaLaTeX and

\documentclass{book}
\usepackage{polyglossia}
\setmainfont{Times New Roman}
\begin{document}
Test
\end{document}

I get

in the page header. Maybe this is related to [#203].

Just to note: It does not happen, if I use fontspec instead of polyglossia.

This is a duplicate of #650, not a polyglossia bug... If you have questions about how to deal with that free to ask here but I'm closing this ticket.
