XeLaTeX, set mono font after loading unicode-math and modify \parfillskip leads to big whitespace in \texttt #632

Description

With XeLaTeX, if one \setmonofont after loading unicode-math, and then modify the \parfillskip, there would be issue with the spacing in \texttt.

This problem does not happen with LuaLaTeX.

See https://tex.stackexchange.com/q/711456.

Minimal example demonstrating the issue

\documentclass{article}
\usepackage{fontspec}
\usepackage{unicode-math}
\setmonofont{NewCMMono10-Regular.otf} % any other typewriter font would do

\begin{document}

\setlength{\parfillskip}{0pt plus 10pt}

\texttt{some text with whitespaces}

\texttt{some-text-with-whitespaces}

\end{document}

Thanks for the report. How bizarre. Confirming this problem does NOT arise when fontspec is loaded without unicode-math.

@wspr Ulrike commented at tex.sx that you can reproduce with just fontspec by declaring the font twice https://tex.stackexchange.com/questions/711456/xelatex-set-mono-font-after-loading-unicode-math-and-modify-parfillskip-leads#comment1767977_711456
