[NTG-context] horizontal list turns into vertical list in framedtext. A bug or feature?

I am just wondering if this is a bug or feature or some lack of understanding on my part. The horizontal list turns into a vertical list inside a framedtext environment. The same happens in a background environment. \starttext \startframedtext[width=\textwidth] \startitemize[5, columns, four] \item Excellent student \item Good student \item Mediocre student \item Poor student \stopitemize \stopframedtext \stoptext -Hamid
