[NTG-context] Vertical space with "alternative=middle" for unnumbered sections

Hi, when I use \setuphead[alternative=middle] with a unnumbered header (e.g. \title) I still get the vertical space where the counter is placed, is this intended? \setuphead   [chapter]   [alternative=middle] \showframe[text][text] \starttext \chapter{Chapter} \title{Title} \stoptext Wolfgang
