Is there a way to get \textfraction to produce output in cases B or C
(either one will do) as it does in case A?

If I use \vfrac the output does not sit well beside \textfraction
output—and I use the latter elsewhere throughout the document.


\definefontfeature[fraction][frac=yes]
\definehighlight[textfraction][style={\feature[+][fraction]}]

\starttext

A. \textfraction{1/2}

B. \textfraction{1.5/2}

C. \textfraction{{2\textfraction{1/2}}/7}

\stoptext
