修改作者字体格式后，第一条参考文献前出现不期望的缩进

[F2E-uni]

问题描述：
我的目标是在参考文献中更改作者格式（对应的代码在最后四行），但为何在第一条参考文献前出现大量不期望的缩进（如下图所示）。完整代码如下所示：

已做的尝试：

• 不使用AtBeginBibliography，那么缩进的问题消失，但正文中第一个文献出现的地方出现缩进
• 不使用AtBeginBibliography和\mkbibnamefamily和\mkbibnamegiven，使用\renewcommand{\bibauthorfont}{\sffamily}，缩进的问题消失，但正文中作者的et al字体格式也变为无衬线，且参考文献中非J类文献的书名也变为无衬线格式
• 不使用\mkbibnamefamily和\mkbibnamegiven，使用AtBeginBibliography和\renewcommand{\bibauthorfont}{\sffamily}，缩进的问题存在

\usepackage[
backend=biber,
style=gb7714-2015,
gbpub=false,
gbnamefmt=lowercase,
sorting=none,
url=false,
doi=false,
]{biblatex}

\addbibresource{ref/ref.bib}

% 设置参考文献每条内的行距
\usepackage{setspace}
\setlength{\bibitemsep}{1.5\itemsep}

% 设置参考文献格式
\DeclareFieldFormat[article,periodical]{volume}{\color{my_orange}\textbf{#1}}
\DeclareFieldFormat{journaltitle}{\textit{#1}}
\renewcommand{\bibpubfont}{\color{pub_gray}}
\AtBeginBibliography{%
\renewcommand*{\mkbibnamefamily}[1]{\sffamily #1}%
\renewcommand*{\mkbibnamegiven}[1]{\sffamily #1}%
}%

1. 没有复现你的现象，你可以更新一下biblatex-gb7714-2015试试。

2. 我看你的需求是只要作者姓名非衬线，然后etal等不用。那么不能用sffamily，要用textsf，比如：

\renewcommand*{\mkbibnamefamily}[1]{\textsf{##1}}%
\renewcommand*{\mkbibnamegiven}[1]{\textsf{##1}}%

3. 如果\AtBeginBibliography带来问题，那么可以在\bibauthorfont中修改
   比如：

\renewcommand{\bibauthorfont}{\color{gray}%
\renewcommand*{\mkbibnamefamily}[1]{\textsf{##1}}%
\renewcommand*{\mkbibnamegiven}[1]{\textsf{##1}}%
}

4. 示例：

% !Mode:: "TeX:UTF-8"
% 用于测试gb7714-2015样式，对于作者姓名格式的控制和选项
% 测试gbnamefmt选项
% 测试bib文件中的nameformat域

\usepackage{hyperref}
\usepackage{lipsum}
\usepackage[top=10pt,bottom=10pt,left=1cm,right=1cm]{geometry}

\usepackage[backend=biber,style=gb7714-2015,gbnamefmt=lowercase,gbalign=center,
gbpub=false,
url=false,
doi=false,]{biblatex}
%gbnamefmt=givenahead,lowercase,familyahead,pinyin

感谢您的解答~经过排查，不是[biblatex-gb7714-2015]包的问题，是我全局改变了normalsize，导致了该问题。现问题已解决

% 全局设置equation环境与正文的间距
% \expandafter\def\expandafter\normalsize\expandafter{%
% \normalsize
% \setlength\abovedisplayskip{1ex}
% \setlength\belowdisplayskip{1ex}
% \setlength\abovedisplayshortskip{1ex}
% \setlength\belowdisplayshortskip{1ex}
% }
