it's a different issue

one of the 'features' of framed is that (in mkii as well as mkiv) it can 
determine the minimum width of a paragraph and orientation doesn't work 
well with that

in the source you will find a comment:

\pack_framed_stop_orientation % hm, wrong place ! should rotate the 
result (after reshape)

if you move that line to after

    \edef\p_framed_empty{\framedparameter\c!empty}%
    \ifx\p_framed_empty\v!yes
      \pack_framed_fake_box
    \fi
\pack_framed_stop_orientation % here

you get what you expected ... but ... such a change can only happen when 
we're sure it work out okay always
