消除由于 setspace 设置而导致的单个脚注（以及显示在页面底部的脚注）内不需要的垂直间距

我正在写一篇论文，并添加了一些旧代码来实现引用样式，其中简短的引用与附加脚注一起放在页面底部。这需要 manyfoot 包，下面给出的代码基于以下问题：

Biblatex 仅引用一次脚注，并使用括号和 Biblatex footcite：自定义 biblatex 和参考书目样式 和 如何删除 doi 字段中的前缀（如果存在）

我正在使用 newpxtext 包，希望整个文档（包括标题、脚注等）的行距略有增加，文本的行距更明显。如果我理解正确的话，这应该通过以下方式实现

\linespread{1.05}
\usepackage{setspace}
\setstretch{1.3}

不幸的是，setstretch 设置会导致脚注内出现不必要的间距，但只会在单个脚注的行之间出现（！），而不会在两个不同的脚注之间出现（见图片）。这与我在几个问题中读到的相反（例如双倍行距和在脚注中设置 1.5 行间距）。如果我排除setstretch命令，脚注内的垂直间距看起来是统一且正确的。

如何摆脱较长脚注（对于脚注A和脚注B）中的额外间距并实现所需的间距？

setspace通过重新定义来明确重置脚注中的行距，\@footnotetext以包含

\def\baselinestretch {\setspace@singlespace}%

在您的设置中，您只使用由 控制的脚注manyfoot，它不会调用\@footnotetext也不会被 修补setspace。

我们可以通过重新定义setspace等价于manyfootmanyfoot\@footnotetext

\makeatletter
\long\def\MFL@fnoteplain#1#2#3{\NCC@makefnmark{#2}%
  \MFL@insert#1{\def\baselinestretch {\setspace@singlespace}%
    \reset@font\footnotesize
    \interlinepenalty\interfootnotelinepenalty
    \hsize\MFL@columnwidth \@parboxrestore
    \protected@edef\@currentlabel{\@thefnmark}%
    \color@begingroup
      \MFL@applyhook{#1}%
      \@makefntext{%
        \rule\z@\footnotesep\ignorespaces#3\@finalstrut\strutbox}%
    \color@endgroup
  }%
}
\makeatother
