I am using this customization How to automatically put a [Go To Summary] | [Go Back] on each section?, but when I load it together with abntex2 class, my go back buttons are put on the next line for the chapter{} command. Everything works fine for section{} and others:

If I remove the following code from the abntex2 class, then, it is fixed:

https://github.com/abntex/abntex2/blob/15a981c300198ca59920eea17f02893490adf878/tex/latex/abntex2/abntex2.cls#L603-L614

  defprintchaptertitle##1{%

    chaptitlefont%

    ifthenelse{boolean{abntex@innonumchapter}}{centeringABNTEXchapterupperifneeded{##1}}{%

    ifthenelse{boolean{abntex@apendiceousecao}}{%

        centering%

        settowidth{chapternamenumlength}{printchapternameprintchapternumafterchapternum}%

        ABNTEXchapterupperifneeded{##1}%

      }{%

        settowidth{chapternamenumlength}{printchapternameprintchapternumafterchapternum}%

        parbox[t]{columnwidth-chapternamenumlength}{ABNTEXchapterupperifneeded{##1}}}%

     }

  }

This is my minimal example:

documentclass[

10pt,

a5paper

]{abntex2}



usepackage[utf8]{inputenc}

usepackage[T1]{fontenc}

usepackage{xcolor}



definecolor{ultramarine}{RGB}{0,32,96}

RequirePackage{amssymb}

newcommand{goToSummaryText}

{%

    smallmdseries

    hyperlink{summary}{textcolor{ultramarine}{$leftleftarrows$}}

    {$|$}

    Acrobatmenu{GoBack}{textcolor{ultramarine}{$leftarrow$}}

}

makeatletter

    newififismemoirloadedismemoirloadedfalse

    @ifclassloaded{memoir}

    {%

        ismemoirloadedtrue

    }{}

    newcommand{addGoToSummary}

    {%

        renewcommand{Sectionformat}[2]{##1 protectgoToSummaryText}

        ifismemoirloaded

            letoldprintchaptertitleprintchaptertitle

            renewcommand{printchaptertitle}[1]{oldprintchaptertitle{##1} protectgoToSummaryText}

        elsefi

    }

    newcommand{removeGoToSummary}

    {%

        renewcommand{Sectionformat}[2]{##1}

        ifismemoirloaded

            letprintchaptertitleoldprintchaptertitle

        elsefi

    }

makeatother

letoldtableofcontentstableofcontents

renewcommand{tableofcontents}

{%

    hypertarget{summary}%

    oldtableofcontents%

}



begin{document}

    addGoToSummary

    chapter{Section contents}

    thing2.

end{document}

How can I patch abntex2 class or my command to fix this issue?
