Comment (by boonebgorges):

 In [changeset:"31792"]:
 {{{
 #!CommitTicketReference repository="" revision="31792"
 In `wp_insert_term()`, allow a term with an existing name if a unique
 `$slug` has been provided.

 `wp_insert_term()` protects against the creation of terms with duplicate
 names
 at the same level of a taxonomy hierarchy. However, it's historically been
 possible to override this protection by explicitly providing a value of
 `$slug`
 that is unique at the hierarchy tier. This ability was broken in [31734],
 and
 the current changeset restores the original behavior.

 A number of unit tests are added and refactored in support of these
 changes.

 See #17689 for discussion of a fix that was superceded by [31734]. This
 commit
 retains the fix for the underlying bug described in that ticket.

 See #31328.
