Manually setting \fontdimen3 and \fontdimen4 seems to correctly change the
space stretchability - and in fact is the workaround I'm using for the
time being - but it must be repeated after every size change and so it
breaks semantic markup. That is the case even with no use of WordSpace in
the document at all.
Sorry I'm late to this discussion. Been overly busy.
This is pretty clearly a bug in the WordSpace feature.
The code here is
\dim_set:Nn \@tempdima {#1\fontdimen2\zf@basefont}
\dim_set:Nn \@tempdimb {#2\fontdimen3\zf@basefont}
\dim_set:Nn \@tempdimc {#3\fontdimen4\zf@basefont}
...
\tl_put_right:Nx \l_fontspec_postadjust_tl {
\fontdimen2\font\the\@tempdima
\fontdimen3\font\the\@tempdimb
\fontdimen4\font\the\@tempdimc
}
which is later used internally in \DeclareFontShape:
\DeclareFontShape{\zf@enc}{\zf@family}{#2}{#3}
{\l_fontspec_nfss_tl}{\l_fontspec_postadjust_tl}
So it seems like I should be writing something more like
\tl_put_right:Nn \l_fontspec_postadjust_tl {
\fontdimen2\font=#1\fontdimen2\font
\fontdimen3\font=#2\fontdimen3\font
\fontdimen4\font=#3\fontdimen4\font
}
instead. Does this seem right? (This code dates back years and years,
so I might not have known what I was doing when this was first written.)
If replies could be CC-ed to me via email I'll be more likely to respond :)
Cheers,
Will
