Different string count in engage banner pulled by Mastodon

[buhtz]

In this picture you see the engage link of my own project, once in a Mastodon post where Mastodon by itself load an engage-banner and the original engage page. The string count differs.

The engage URL: https://translate.codeberg.org/engage/backintime/
The Mastodon post: https://fosstodon.org/@backintime/114109368258731060

Do you have an idea why this happens?

I do assume that the string count from Glossary is added to the count used in the Mastodon picture.

I am using the Weblate instance at translate.codeberg.org with version 5.10.2.
Maybe related issue: #10094 and commit ed44a52

Now tracked as #14218 (not sure why GitHub didn't link this automatically).
