Hello,

There seems to be a bug in RTL documents when \framed goes in \leftaligned,
\midaligned, or \rightaligned AND corner=round option is used.  (I don't
know what other options trigger the bug.)

Here is the MWE (verified in ConTeXt ver: 2016.01.18 22:21 MKIV beta fmt:
2016.1.19 int: english/english):

\setupalign[r2l]
\starttext

\midaligned
  \framed[corner=round,
               width=.5\hsize]
         {Hello!  This is some sample text.}

\stoptext

It works fine when either corner or midaligned is dropped.  With both in,
however, the frame appears to the right of the text (no overlap).

Thanks!
