the width=fit option will decompose the box try - as best as can do done with current tex- determine the fittign width; 

in the process, spacing may disappear 

also, framed may place struts automatically 

this may work: 

\startframedtext[middle][width=fit]
\strut\endgraf
\type{extra vertical space}\endgraf
\type{normal vertical space}\endgraf
\strut\endgraf
\stopframedtext

as may this: (smaller strut) 

\startframedtext[middle][width=fit,strut=no]
{\setupstrut[x]\strut}\endgraf\nointerlineskip
\type{extra vertical space}\endgraf
\type{normal vertical space}\endgraf
{\setupstrut[x]\strut}\endgraf\nointerlineskip
\stopframedtext


another option is to do something: 

\framed [width=fit,offset=overlay] \bgroup
  \vskip 1ex
  \quad \framed[width=fit,frame=off] \bgroup
      your content 
  \egroup \quad 
  \vskip 1ex
\egroup

or alike
