WPML: Preload Secondary Language

Hi,

if I activate "Cache preload", only the Main Language is getting cached. But not the secondary language (English).

Is there a way to make this work?

How exactly does the plugin work to find all posts and pages?

Reproduce the issue with WPML enabled, Cache preload active, and separate primary and English content. Trace how the plugin discovers posts and pages for preloading, then verify that secondary-language URLs are included and document how discovery works. No files or tests are named in the issue.
