The module parameters are also used in the plugin with demo data. We probably need to make changes in file plugins/sampledata/blog/src/Extension/Blog.php, because demo data creates 3 modules of type ARTICLES after installation.

UPD
Or do it after merging about 5 new PRs for this module.

This was merged with wrong context, what happened? 😄

Adding the mod_articles context will not load the custom fields. It needs to go through com_content or else information will be missing. I didn't feel like change plugin events.
