I would not have expected differently than that this works!

If you use this mechanism, the frame will have to be set to off. If you
still want to change the  thickness of the dashed box you will do this in
the Metapost code. Then it will be time to consult the Metafun manual  ;-)

 \startuniqueMPgraphic{dashed}
      pickup pencircle scaled 2pt
     draw OverlayBox dashed evenly ;
 \stopuniqueMPgraphic
