看到 lsp-ui 添加了 webkit 渲染文档的功能 https://github.com/emacs-lsp/lsp-ui/pull/221 就想体验一下，于是便编译了最新的 emacs 发现精度提高了好多啊
PS： 对了，新版 emacs 还添加了新的补全方式
New ‘flex’ completion style
An implementation of popular "flx/fuzzy/scatter" completion which matches strings where the pattern appears as a subsequence. Put simply, makes "foo" complete to both "barfoo" and "frodo". Add 'flex' to 'completion-styles' or 'completion-category-overrides' to use it.
