Letters inside $..$ without other markup are not set in \mathrm but in
\mathit; and \setmathrm only changes \mathrm.  If you change that line to:

$\mathrm{abcdefgh}$\\

then it sets the letters in monospace.  I don't know how to change the
behaviour of \mathit; fontspec doesn't seem to have a \setmathit command,
and it looks like that one may be more complicated to change than \mathrm.
