A reference to the text of a multi-line heading takes on the line breaks of the heading when \definereferenceformat[about] is used.
\definereferenceformat[about][type=title,left=,right=]
\starttext
\startsection[reference={sec:one},
  title={Three\\line\\title}]
\startparagraph
See \about[sec:one].
\stopparagraph
\stopsection

\stoptext
Can this be repaired? Or, am I doing it wrong?
