[NTG-context] Different behaviours between header and footer

Dear all, in the following example, header and footer behave differently, the frame at the bottom being out of the footer space. Could you tell me how to obtain a frame inside the footer like the header one? Thanks a lot, Flavien. \setupheadertexts[{\framed[frame=off,width=\textwidth,height=\headerheight]{not offset}}][] \setupfootertexts[{\framed[frame=on,height=\footerheight]{offset}}][] \showframe \starttext \input knuth \stoptext
