When I have:

\subsubsection{Foo}
\startitemize[joinedup,packed]
\item Bar
\item Bar
\item Bar
\stopitemize

TeX may put a page break between the heading and the paragraph. Is there a way to prevent this? I tried

\subsubsection{Foo}\page[no]
\startitemize[joinedup,packed]
\item Bar
\item Bar
\item Bar
\stopitemize

and 

\subsubsection{Foo}
\startitemize[joinedup,packed]\page[no]
\item Bar
\item Bar
\item Bar
\stopitemize

but both did not work. I can of course force with

\page[yes]\subsubsection{Foo}
\startitemize[joinedup,packed]
\item Bar
\item Bar
\item Bar
\stopitemize

but that is not ribust under change in the document.
