\vskip-\baselineskip after section header in mkIV

\vskip-\baselineskip after section header in mkIV

[Vianney le Clément]

Hello,

\vskip-\baselineskip behaves strangely when put after a section
header. Here is a minimal example.

\setuphead[subject][after=]
\starttext
\subject{Header}
\vskip-\baselineskip
Text
\stoptext

One would expect to have "Header" overprinted by "Text". This is the
case in mkII, but not in mkIV where we get "Header" followed by "Text"
on the same line. Is this a bug or a feature?
Also interesting is when you add \setuphead[subject][style=] in the
preample, then the behavior is like mkII.

BTW, if you wonder why I'm using this, I want to put some additional
info on the right side of the title when there is room left. Otherwise
it should be put just below.

Thanks,
Vianney

Text

\subject{Header}

\vskip-\the\dimexpr\baselineskip+1sp\relax \par

Text

\subject{Header}

\vskip-2\baselineskip \par

This appears to be a bug in the luatex pdf backend.

Best wishes,
