I'd like to use a drop cap inside a \framed, but it doesn't work.

Minimal example:

%==========================
\starttext
\setupinitial[n=2,text=Knuth]\placeinitial\input knuth

\framed[align=flushleft]{\setupinitial[n=2,text=Knuth]\placeinitial\input knuth }
\stoptext
%==========================

The first drop cap works, the second is empty.
