[NTG-context] Problem with letter size in \SmallCapped and enumerations

[NTG-context] Problem with letter size in \SmallCapped and enumerations

[Matthias Weber]

When I include a descriptive text in an enumeration in SmallCapped, the last letter sometimes gets somewhat large. 
It only happens with alternative=serried, and only in some fonts. Below an example (thanks to Wolfgang for showing how to loop over fonts).

I use Pagella, where I first noticed it. What precisely does “serried” do?

Thanks, 

Matthias


\defineenumeration
  [Unserried]
  [text=Unserried,
 % alternative=serried,
   width=fit,
   title=yes,
   titlestyle=normal,
   prefix=yes]
   
   \defineenumeration
  [Serried]
  [text=Serried,
   alternative=serried,
   width=fit,
   title=yes,
   titlestyle=normal,
   prefix=yes]
   
\starttext

\doloopoverlist
   {bonum,cambria,concrete,dejavu,ebgaramond,erewhon,kpfonts,
    libertinus,lucida,modern,pagella,schola,stixtwo,termes,xcharter}
   {\switchtobodyfont[\recursestring]
    \recursestring: 

\startUnserried{\SmallCapped{Sliding}}
\stopUnserried

\startSerried{\SmallCapped{Sliding}}
\stopSerried
\par}
\stoptext

It's one of the rare situations where we unhbox something which means 
that the node list gets processed twice and then the fonts kern interferes.

\showfontkerns

I will fix it (and then probably need to check a few more handlers) but 
here is a quick hack (different solution) that you can put in cont-new.mkxl:

\permanent\protected\def\flushconstructionheadbox
   {\ifhbox\constructionheadbox
      \scratchdimen\boxrepack\constructionheadbox
    \fi
    \box\constructionheadbox}

which might work ok here.
