Using glossaries-extra to define an entry accepting a parameter results in a leading dot

I'm using glossaries-extra to define glossaries entries accepting parameters. To what I gathered from the glossaries documentation along with the fourth method of this post, I ended up with the following MWE.

\documentclass{book}

\usepackage[hidelinks]{hyperref}
\usepackage[debug=all, automake]{glossaries-extra}
    \newglossary[slg]{symbolslist}{syi}{syg}{Notations}
    \makeglossaries

\newcommand{\orthogonal}[1]{\ensuremath{\mathcal{O}_{#1}}}
\newglossaryentry{orthogonal}{%
    user1={orthogonal},%
    name=\ensuremath{\orthogonal{d}},%
    description={The orthogonal group in dimension \(d\)},
    type=symbolslist
}

\begin{document}

Here's \gls{orthogonal} and \glsxtrfmt{orthogonal}{5} and \glslink{orthogonal}{\orthogonal{7}}.

\printglossaries

\end{document}

However, this results in a weird dot appearing before the printing of the \gls and \glslink commands. Why is that the case, and how could I remove it?
