Overfull hbox due to `glossaries-extra`

Question

As identified based on another of my questions here. Warnings like

Overfull \hbox (28.00505pt too wide) in alignment at lines 46--46

seem to be produced when using the glossaries-extra package.

Here is a MWE which outputs 3x the warning I mentioned.

The test.tex looks like

%!TEX root = test.tex
%!TEX program = latexmk
%!TEX encoding = UTF-8 Unicode
%!TEX spellcheck = en-US
\RequirePackage[l2tabu,orthodox]{nag}
% \RequirePackage{luatex85}
% \documentclass[a4paper,11pt,abstract=true]{scrreprt} % this is the main file
\documentclass[a4paper,11pt]{scrbook}
% \usepackage{refcheck}
% \usepackage{showkeys}
% for info on KOMA script see
% http://www.golatex.de/wiki/KOMA-Script
% fix incompatibilities of some packages with KOMA script
\usepackage[automark,headsepline=.5pt]{scrlayer-scrpage}
\usepackage{siunitx} % add SI unit convention support
\usepackage[record,% using bib2gls
    symbols, % create list of symbols
    stylemods={longextra}, % load glossary-longextra.sty
    nogroupskip
]{glossaries-extra}
\GlsXtrLoadResources[
    src={symbols}, % data in symbols.bib
    sort-field={name}, % sort by name field
    sort={letter-nocase}, % case-insensitive letter sort
    type=symbols, % put these terms in the symbols list
    field-aliases={unit=symbol},% convert unit key to symbol
    save-locations=false, % don't save location lists
    selection={all}, % print all without using
]
\begin{document}
\renewcommand{\symbolname}{Unit}
\renewcommand{\glslongextraNameAlign}{c}
\renewcommand{\glslongextraSymbolAlign}{r}
\printunsrtglossary[type=symbols,style=long-name-desc-sym]
\end{document}

and the symbols.bib is

% Encoding: UTF-8
% requires siunitx.sty
@symbol{cP,
  unit = {\si{\square\metre\per\square\second\per\kelvin}},
  name = {\ensuremath{c_P}},
  description = {Specific heat at constant pressure}
}

probably you should mention (as it took me a while to discover) this needs pdflatex, bib2gls, pdflatex — David Carlisle, Jan 25 '21 at 14:46
Ohh yes, sorry for not specifying it, one should run bib2gls -d <path to build dir> test inbetween. — Stefan, Jan 25 '21 at 15:28

The problem is that due to the width of the entries, the longtable used for the table is too wide.

The fixed-width description column is set in the style you are using by

\newcommand{\glslongextraDescAlign}{>{\raggedright}p{\glsdescwidth}}

So the correct solution is most likely to set \glsdescwidth to be 30pt less but I couldn't see where it is set (I don't know this package) and just reducing it in the preamble by 30pt had no effect so I instead I used

\renewcommand{\glslongextraDescAlign}{>{\raggedright}p{\dimexpr\glsdescwidth-30pt}}

so longtable used 30pt less than it previously used for the middle column and the table then fits the page.
