Describe the current, buggy behavior
I really like to automate my content export with "wp export", it's very easy and fast, but.
Аfter upgrading to WP 5.8 in the file content.xml missing data "cat_name, tag_name, term_name" because of this when importing errors.

I found a temporary solution wp eval "require_once ABSPATH . 'wp-admin/includes/export.php'; export_wp( [ 'content' => 'all' ] );"

It looks like this is unrelated to WP 5.8, but is rather a regression that was introduced via #84 .
