Überschriftenhöhe und Raster in ConTeXT

Question

Wie erhöhe ich die Zeilenhöhe von Überschriften in ConTeXT, während ich den Rastersatz verwende, ohne die Ausrichtung nachfolgender Zeilen zu beeinträchtigen? (Fehlausrichtung grün markiert).

Mein Code ist:

\definefontfeature[default][default][protrusion=quality,expansion=quality,liga=yes,onum=yes]
\setupalign[hanging,tolerant]
\setuppapersize[A5][A5]
\setupinterlinespace[line=16pt]
\setuplayout[
                grid=yes,
               width=fit,
              height=fit,
            location=middle,
            topspace=0.2in,
         bottomspace=0in,
              bottom=0.2in,
           backspace=0.75in,
            cutspace=0.5in,
          leftmargin=0.2in,
         rightmargin=0.75in,
  leftmargindistance=0.1in,
 rightmargindistance=0.1in,
              header=0.20in,
              footer=0.20in,
      headerdistance=0.2in,
      footerdistance=0.2in
]
\setuppagenumbering[
   alternative=doublesided,
      location={footer, right, margin},
         width=1in,
         right={\hfill},
          left={\hfill}
]
\setupheads[indentnext=no]
\setupindenting[yes, small]
\setupmargindata[inmargin][location=right, style=small]
\definepagebreak[mychapterpagebreak][yes,header,right]
\setuphead[chapter][
     page=mychapterpagebreak,
    style=\tfc,
textstyle={\kerncharacters[.5‌​]},
   % If I remove \setuplocalinterlinespace here, I get the alignment right.
   before={\ \blank[2*big]\setuplocalinterlinespace[line=3.2ex]},
    after={\blank[3*big]},
   number=no
]

Answer 1

Das \setuplocalinterlinespace[line=3.2ex]scheint aus der Definition des Kapitels herauszusickern. Verwenden Sie interlinespacestattdessen einfach die Option. Außerdem müssen Sie vor einen Absatz beginnen \blank[2*big], da Sie sonst auch den vertikalen Abstand stören.

\definefontfeature[default][default][protrusion=quality,expansion=quality,liga=yes,onum=yes]
\setupalign[hanging,tolerant]
\setuppapersize[A5][A5]
\setupinterlinespace[line=16pt]
\setuplayout[
                grid=yes,
               width=fit,
              height=fit,
            location=middle,
            topspace=0.2in,
         bottomspace=0in,
              bottom=0.2in,
           backspace=0.75in,
            cutspace=0.5in,
          leftmargin=0.2in,
         rightmargin=0.75in,
  leftmargindistance=0.1in,
 rightmargindistance=0.1in,
              header=0.20in,
              footer=0.20in,
      headerdistance=0.2in,
      footerdistance=0.2in
]
\setuppagenumbering[
   alternative=doublesided,
      location={footer, right, margin},
         width=1in,
         right={\hfill},
          left={\hfill}
]
\setupheads[indentnext=no]
\setupindenting[yes, small]
\setupmargindata[inmargin][location=right, style=small]
\definepagebreak[mychapterpagebreak][yes,header,right]

\setuphead[chapter][
     page=mychapterpagebreak,
    style=\tfc,
textstyle={\kerncharacters[.5‌​]},
   % If I remove \setuplocalinterlinespace here, I get the alignment right.
   before={\dontleavehmode\blank[2*big]},
   after={\blank[3*big]},
   interlinespace=3.2ex,
   number=no,
