Description
Without using the package, there is negative kerning between "P." (\kern-0.83334 in the .log).With acronym commands, which expand to the same text, kerning between "P." is prevented.
This is analogous to https://tex.stackexchange.com/questions/680723/acro-package-bug-with-kerning, but with the glossaries package.

\documentclass{article}
\usepackage[nomain,acronym]{glossaries}
\newacronym{op}{OP}{Operator}
\begin{document}
\showoutput
OP. foo.
\acrshort{op}. foo.
\end{document}
Evaluation
The problem is the same as that mentioned in the referenced TeX on StackExchange question for the acro package. It can be demonstrated with \index which is essentially the same mechanism as used by both glossaries and acro:
\documentclass{article}
\begin{document}
\showoutput
OP.
OP\index{OP}.
\end{document}
However, the problem is not just the indexing whatsit but also the first use conditional, which can be demonstrated with:
\documentclass{article}
\begin{document}
\newif\iffirstuse
\firstusetrue
\showoutput
OP.
OP\firstusefalse.
\end{document}
The indexing whatsit can be moved to the start with glossaries-extra's wrgloss setting:
\usepackage[nomain,acronym]{glossaries-extra}
\setabbreviationstyle[acronym]{short-long}
\newacronym{op}{OP}{Operator}
\GlsXtrSetDefaultGlsOpts{wrgloss=before}
However, the conditional can only be changed after the link text because the link text depends on that conditional. This unfortunately means that there's no fix for this issue.
The only workaround is to move the punctuation into the link text with the final optional argument. For example, with just the base glossaries package:
\acroshort{op}[.]
Or with glossaries-extra:
\glsxtrshort{op}[.]
Or with either:
\gls{op}[.]Comments
