无法将 cas-sc 格式的 latex 中摘要的行距加倍用于 elseiver

当我的稿件被退回时，我在使用 cas-sc LaTeX 模板时遇到了麻烦。编辑回复说：

键入所有的稿件双倍行距。

我引用了Campa 的回答并添加了\doublespacing之后\maketitle，我也添加了\doublespacing之后\keywords。但无论我做什么，抽象的不能双倍行距。以下代码是该问题的最小样本。

\documentclass[a4paper,fleqn]{cas-sc}

\usepackage[square,sort,comma,numbers]{natbib}
\let\printorcid\relax
\usepackage{lscape}
\usepackage{setspace}

\ExplSyntaxOn
\keys_set:nn { stm / mktitle } { nologo }
\ExplSyntaxOff


\begin{document}
    \let\WriteBookmarks\relax
    \def\floatpagepagefraction{1}
    \def\textpagefraction{.001} 
    % Main title of the paper
    \title [mode = title]{This is title}  
    
    %%%%%%% second author %%%%%%%
    \author[1]{A person}
    \ead{[email protected]}
    \credit{}

该命令\doublespacing很脆弱，请将其与以下内容一起使用\protect：

\begin{abstract}
  \protect\doublespacing
  this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract this is abstract
\end{abstract}

\protect更多信息脆弱命令和坚固命令之间有什么区别？什么时候以及为什么我们需要 \protect？
