context.delayed is incompatible with some functions

context.delayed is incompatible with some functions

Dear List,

I was reading Typesetting in Lua using LuaTEX
<https://www.ntg.nl/maps/41/11.pdf>. By playing with the examples in the
article, I found that
  `context.chapter(context.delayed("one"))`
does not render the delayed text properly, while
  `context.bf(context.delayed("one"))`
does.

I would like to ask whether this difference is by design and, if not,
whether there is any systematic way of giving delayed arguments to
`context.chapter`, where by "systematic way" I'm referring to a proper use
of the existing definition of "\chapter" instead of any faked duplication
of it that visually resembles a chapter title.

Thanks in advance.

Best,
Sylvain

by design

\ctxlua{context.chapter(context.delayed("one"))}

\setuphead[chapter][expansion=yes]

\ctxlua{context.chapter(context.delayed("one"))}
