Comment (by manooweb):

 It's seems that we also have issues when
 - adding a term in this kind of taxonomy
 - trying to delete a taxonomy just after adding the new term

 It was observed with WooCommerce product attribute terms.
 I described what happens in a WooCommerce issue.

 It espacially come from we can add a term in ajax because the taxonomy
 slug isn't sanitized in wp_ajax_add_tag() function before inserting the
 term.
 See https://github.com/WordPress/WordPress/blob/6.8/wp-admin/includes
 /ajax-actions.php#L1089-L1100

 WooCommerce doesn't sanitize the product attribute slug enough (sanitize
 title() instead of sanitize_key()) which causes theses issues in the terms
 screen.

 Related WooCommerce issue, maybe closed too quickly I think 🤔
