there is no linebreak in the text because it's a boxed content, a simple
version of my macro is
\def\pdfactualtext#1#2%
{\pdfliteral direct{/Span <</ActualText
\ctxlua{tex.write(lpdf.tosixteen("#2"))} >> BDC}#1\pdfliteral direct{EMC}}
\def\ruby#1#2%
{\dontleavehmode\bgroup
\setbox\scratchboxone\hbox{#1}%
\setbox\scratchboxtwo\hbox{#2}%
\scratchdimen\wd\scratchboxone
\setbox\scratchbox\vbox
{\hbox to \scratchdimen{\hss\box\scratchboxtwo\hss}
\hbox to \scratchdimen{\hss\box\scratchboxone\hss}}%
\pdfactualtext{\box\scratchbox}{#1 (#2)}%
\egroup}
\starttext
text \ruby{base text}{ruby text} text
\stoptext
