Sangría después de un título usando "alternativo=texto"

Question

Estoy usando ConTeXt 2018.04.04 de TeXLive 2018. Cuando uso la alternative=textopción en \setuphead, el segundo párrafo después del título no tiene sangría. No puedo encontrar en el manual cómo sangrarlo.

Aquí hay un ejemplo mínimo:

\setupindenting[yes,big]
\setuphead[section][alternative=text]
\starttext
\section{Introduction}
\input knuth
\stoptext

Cuando agrego la siguiente opción, no cambia nada:

\setuphead[section][alternative=text,indentnext=yes]

En el ejemplo, quiero que el párrafo que comienza con

La separación de cualquier...

tener sangría, pero no lo es.

El problema también aparece en la última versión beta. Aparentemente el problema se introdujo al arreglar otro error, porque al comentar la línea

\noindentation % recently added, was a bug

soluciona \strc_rendering_stop_placementel problema. Esto se ha informado en la lista de correo:https://mailman.ntg.nl/pipermail/ntg-context/2019/094251.html
