WordPress Importer does not remap noteId in block metadata when reassigning comment IDs

[tenacityio]

Steps to reproduce:

1. Create a post/page with block notes (WP 6.9 Notes feature)
2. Export via Tools → Export
3. Import the WXR file into another site (or same site) via the WordPress Importer
4. Open the imported post in the editor

Expected: Notes appear attached to their respective blocks

Actual: Notes import as comments but are unlinked from blocks. The importer assigns new comment_id values but does not update the corresponding "noteId":N values in block metadata within post_content.

Workaround: Post-import script that remaps noteId references in post_content to the new comment_id values by matching on insertion order.

I thought this might be a problem with footnotes as well, but a footnote use a UUID as its ID, not any underlying auto-incremented ID.

Hi @westonruter @tenacityio, I guess we need to fix it in upstream repo here ​https://github.com/WordPress/wordpress-importer/?

If Yes, I do have a PR ready for the same - ​https://github.com/WordPress/wordpress-importer/pull/254

Thanks,
