使用 combofont 设置无衬线数学字体：大积分错误

我目前正在尝试使用组合字体在 lualatex 中构建无衬线字体。为了进行测试，我使用 TeX Gyre Pagella Math 作为基础数学字体，并尝试从其他数学和文本字体中提取字形。

它已经适用于数字和字母，但现在我被积分卡住了。我可以使用 TeX Gyre Dejavu Math 的 textstyle 积分，但 displaystyle 积分是错误的。有人知道如何纠正这个问题吗？

（这是一个测试文件！所以它不会试图变得漂亮。例如，脚本样式字体使用其他权重，以便人们可以更好地看到组合是否有效）。

% better start with a real math font, so that

如果你只是使用unicode-math

% better start with a real math font, so that
% unicode-math sets everything up
\setmathfont{TeX Gyre Pagella Math}%

因此删除所有组合字体，然后添加\showoutput你看到的

.....\l_fontspec_font ∫
....\glue(\thinmuskip) 1.82497
....\l_fontspec_font f

对于文本样式\int f，但是

.......\l_fontspec_font
