The path from international WordPress plugin sites to the Playground is currently still somewhat confusing. If you click on a live preview button on https://de.wordpress.org, for example, you always end up in an English environment - not the German one.

Currently, the plugin-directory plugin calls this URL from the Playground, regardless of which language is actually used:

https://playground.wordpress.net/?plugin=%s&login=1&url=%s

Source: https://meta.trac.wordpress.org/browser/sites/trunk/wordpress.org/public_html/wp-content/plugins/plugin-directory/class-template.php?rev=12931#L734

I think it would be easy to read the language in the plugin-directory plugin. But what would the above URL have to look like for playground to automatically load a requested language?

Example: https://de.wordpress.org/plugins/external-files-in-media-library/ - always loads in an English environment.
