使用“alternative=text”在標題後面縮排

Question

我正在使用 TeXLive 2018 中的 ConTeXt alternative=text2018.04.04 \setuphead。我在手冊中找不到如何縮排。

這是一個最小的例子：

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

當我添加以下選項時，它不會改變任何內容：

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

在範例中，我想要以開頭的段落

任何人的分離...

縮進，但事實並非如此。

這個問題也出現在最新的測試版。顯然這個問題是在修復另一個錯誤時引入的，因為註解了該行

\noindentation % recently added, was a bug
