if a float is too wide it will be moved around; wide floats spanning

At least I didn't overlook something simple :)
Is there any easy fix to prevent the "table" from disapperaring when I
uncomment the \input knuth?
% -*- mode: context; coding: latin-9-unix; -*-
\setuplayout [grid=yes]
\definecolumnset[example]
\setupfloat[table][width=\makeupwidth]
\starttext
\startcolumnset[example]
\input knuth
%\input knuth
\placetable{Tabelle}
  \framed[width=\makeupwidth,height=4cm]{Hallo}
\input knuth
\input knuth
\stopcolumnset
\stoptext
well, you can't blame knuth for that one ... the problem is that the 
graphix is oved to a next page already but that page has no content
