--------------------------+-----------------------------
 When querying for taxonomy terms assigned to certain objects,
 WP_Term_Query's query is LIMIT'ed if the 'number' argument is specified.
 This introduces a problem similar to hierarchical taxonomies where results
 must not be limited in order to retrieve children. In particular, the
 issue arises because each term_taxonomy_id, or "(term, taxonomy) couple",
 has more than one relationship in wp_term_relationships thus more than 1
 row could be returned for the same term_taxonomy_id.

 It is worth to notice that in order to replicate the problem in the
 attached test, the 'order' argument must be set to DESC which is the
 opposite of WP_Term_Query's default.
