[NTG-context] Heading with linebreaks in pdf bookmarks: linebreak sign stays

Hi, as soon I have a linebreak inside a heading via \\ I get this \\ also in the text of that heading in the pdf-bookmarks: \setupinteraction[state=start] \placebookmarks[chapter,section,subsection][chapter,section] \starttext \completecontent[criterium=all] \chapter{A very,\\very long long title} \chapter{A very, very long long title} \stoptext What did I forgot to get rid of the linebreak sign in the pdf bookmarks?
