The documentation on page
http://wiki.contextgarden.net/Description

provides sample code to stack multiple levels of description such as:

\setuppapersize[A5]
\definedescription[descr][

  headstyle=bold, style=normal, align=left, location=hanging, 
  width=broad, margin=1cm
]
\starttext
\startdescr{Para}

  This is a shorter item label, and some text that talks about it.
  The text is wrapped into a paragraph, with successive lines indented.

  This is another paragraph under the "Para" item.
  
\startdescr{Sub Item}
  
    This is a description of an item which is within the "Para" item.
  
\stopdescr
\startdescr{Sub Item}
 
    Another Sub Item 
  
\stopdescr
\stopdescr
\startdescr{Short}

  A short item that's not part of that really long "Para" item.

\stopdescr
\stoptext

which should generate the included rendering.



But reality is somewhat more diverse …
My current context / luatex, as well as the online context engine come up with a different rendering


Even when you correct for the right/left alignment, the itemising does not properly stack up:


It there a work around ?
