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
