[NTG-context] Problem with text floating around tikz picture

[Marcin Borkowski]

Hi again;),

this won't work:

\placefigure[right]{none}{\starttikzpicture
  \draw (0,0) -| (2,2) -| (0,0) -- (2,2)
    (2,0) -- (0,2)
    (1,1) circle(1);
\stoptikzpicture}
(some text...)

The tikzpicture apparently extends to the whole text width, resulting in
an overfull box (and nasty paragraph formatting).  Putting it into an
\hbox helps, so I know what to do; the question is, _why_ this works
that way?
