Context

In a recent change, directly linking to a blog post from the nav exhibits strange behavior. The nav link works, but that specific blog post is missing the metadata sidebar and it is excluded from the blog index.

Bug description

On my site, I link to a specific blog entry under a nav entry called Mission. This normally works fine, but in insiders 9.2.7+4.40.3 I get an error: A reference to 'blog/posts/mission.md' is included in the 'nav' configuration, but this file is excluded from the built site. The nav link works, and it shows the blog entry, but it is missing the blog metadata like date and author. Other posts that aren't linked in the nav show up in the blog index, but the mission.md one is missing.
