Upstream issue: WordPress/gutenberg#41121

To be more specific.

We're using the wp:post-author-name block which only exists within Gutenberg.

Gutenberg 13.2.1 (and maybe others?) don't ship with a navigation-area block, but it's in the Gutenberg Repo + in the blocks file, Gutenberg returns early (instead of just skipping the single file) when a file doesn't exist, and thus, all of the Gutenberg blocks with a name further in the alphabet than 'navigation-area' aren't loaded when Gutenberg is active.
