Message:

I18N: Fix just-in-time translation loading for network-activated plugins.

Just-in-time translation loading depends on text domain paths registered during bootstrap, but only site-level active plugins were registered. In multisite, PHP translation functions therefore returned untranslated strings for network-activated plugins even when the correct translation files were present.

Developed in: ​https://github.com/WordPress/wordpress-develop/pull/11243

Follow-up to r59461.
