 As reported here: https://github.com/WordPress/gutenberg/issues/45811
 after a discussion in slack:

 On wp-themes.com we're running into a use-case where the Parent theme
 cannot be located when both the parent and child theme are block themes,
 and the parent does not have an index.php file.

 (See screenshot attached below, where the parent theme is 100% most
 definitely installed)

 This appears to work on some installations, but not on others. I believe
 it working might be down to caching, I haven't figured that out.

 The attached PR updates the code in WP_Theme to support the same theme
 files as supported via [53416] for themes in parent themes.

Comment:

 I'm not familiar enough with the rest of this code to really figure out if
 the PR is a complete solution, but it appears to work for me.
