[Tex/LaTex] How to remove two lines around blank abstract in Elsevier final output

abstractelsarticlefront-matterrules

I'm using \documentclass[final]{elsarticle} to prepare supplementary materials for a paper I'll be submitting to an Elsevier journal. Obviously there is no need for an abstract here, but I can't figure out how to get rid of the two horizontal lines:

Here is my MWE:

\documentclass[final,3p,times,11pt]{elsarticle}
\usepackage{lipsum}

\begin{document}
    \begin{frontmatter}
        \title{This is the paper you are looking for}
        \author[]{O. Kenobi}
    \end{frontmatter}
    \lipsum[8]
\end{document}

There are at least two related questions addressing this problem for \documentclass[preprint]{elsarticle}, but those solutions don't work for [final]:

Best Answer

The rules are hard-coded in the construction of the title and remain there even if no abstract or keywords are provided. Removing them is best done using a redefinition of \MaketitleBox (or using etoolbox patching):

enter image description here

\documentclass[final,3p]{elsarticle}

\usepackage{lipsum}

\makeatletter
\renewcommand{\MaketitleBox}{%
  \resetTitleCounters
  \def\baselinestretch{1}%
  \begin{center}
    \def\baselinestretch{1}%
    \Large \@title \par
    \vskip 18pt
    \normalsize\elsauthors \par
    \vskip 10pt
    \footnotesize \itshape \elsaddress \par
  \end{center}
  \vskip 12pt
}
\makeatother

\begin{document}

\begin{frontmatter}
\title{This is the paper you are looking for}
\author{O. Kenobi}
\end{frontmatter}

\lipsum[8]

\end{document}

The redefinition is actually just grabbing everything from the original \MaketitleBox up to where the rules are usually inserted. You can adjust the space below the title to suit your needs.
