新的 fontspec 给 xelatex 和 Calibri 带来了问题

Question

运行下面的 MWE 可以正确使用 fontspec 2.6l（Texlive 2018/Win 7 中的 rev 49739），但使用 fontspec 2.7（rev 49809）时会出现错误

% !TeX encoding = UTF-8
% !TeX spellcheck = nl_NL
% !TeX TS-program = xelatex

\documentclass{article}

\usepackage{parskip}
%% Find out what engine we're running...
\usepackage{ifluatex,ifxetex}

%% Different setup for xe
\ifxetex
