Comment (by petitphp):

 == Test Report
 This report validates that the indicated patch addresses the issue.

 Patch tested: https://github.com/WordPress/wordpress-
 develop/pull/5720.diff
 Testing instructions:
 [https://core.trac.wordpress.org/ticket/17379#comment:33 comment:33]

 === Environment
 - OS: macOS 13.6.1
 - Web Server: Nginx
 - PHP: 7.4.33
 - WordPress: WordPress 6.5-alpha-56966-src
 - Browser: Firefox 122b9
 - Theme: Twenty Twenty-Four
 - Active Plugins:
   - WordPress Importer 0.8.2

 === Actual Results
 - ✅ With the patch, exporting posts for a specific author also include
 all the children attachments of the posts and all the attachments used as
 thumbnails.
 - ✅ Importing the XML file with the `Download and import file
 attachments` option checked did correctly create the expected posts with
 their medias/thumbnail.

 === Additional Notes
 - While testing the patch, it appears that the new queries used to find
 related attachments would also run when exporting "Media" where it is not
 useful. I don't think it's a blocker for the current patch to be
 committed. I've added a comment in the PR to discuss a small change to
 avoid those extra queries in this special case.
