具体问题和 #636 类似:

\documentclass{ctexart}

\xeCJKsetup{xCJKecglue=true}

\begin{document}

xeCJK 版本是 v3.9.1, 在 v3.8.8 上没有此问题. 在 Overleaf 上进行测试, 只能筛到 TeX Live 2023 会出问题, TeX Live 2022 没有问题的地步.

和 #636 是同一个问题。#636 的修复提交到在代码仓库后，xecjk（还）没有发新版（最新版依然是 v3.9.1，和 #363 报告时相同）。

我在 https://github.com/CTeX-org/ctex-kit/issues/636#issuecomment-1777564375 回复了一个手动应用修复的临时方案。
