[NTG-context] \startchapter[title = First] didn't show the title.

Hi all, Here is one more question. \starttext \startchapter[title = First] bla bla bla \stopchapter \stoptext In this sample, the title "First" isn't show up. After removing spaces before and after "=" sign, it showed up. It is not a big problem though, but, is it intended? It still remains after the updating. Thanks for reading Best regards, Dalyoung
