this is one of those messy areas where no robust solution is possible
the same can happen with header and footers and such (it does not happen
with color in mkiv because we use attributes)
I wonder, if we add \page here we might solve this kind of problems but
it might also have other side effects ... let's do it for a while (i
probably need to move some code)
\def\stoptext
{\global\advance\textlevel\minusone
\ifnum\textlevel>\zerocount \else
\page % new, flushes headers, colors etc etc etc
\the\everystoptext
\expandafter\finalend
\fi}
