Unable to create 2 categories with the same title under different parents

[DD32]

If you attempt to create 2 categories: \Category1\TestCategory and \Category2\TestCategory, TestCategory will fail to be created under the 2nd category, failing on "The category you are trying to create already exists."

It appears that category_exists() which in turn calls is_term() doesnt support hierarchies, Instead mearly checking to see if a Term with that Name exists within the taxonomy.

Partially related to: #5034

The requirement for a unique name for categories regardless of hierarchy is documented in the codex, so this should be categorized (heh) as a feature request/enhancement rather than a defect.

see #8167, #4603, #5034

This has been "fixed" during #11838 (I assume)

The slugs created seem a bit strange however.. but the Names work.

Eg:

Category: Test
Parent: None
slug: test
URL: /category/test/

Category: Test
Parent: Parent Cat
slug: test-parent-cat
URL: /category/parent-cat/test-parent-cat/

The slugs created seem a bit strange however..

Thats due to the changes made in: (In [6157]) Term with slug that conflicts with existing term with different parent gets a new term entry with a unique slug. see #5034

Is anyone aware of anything that this will break?

Can't we close this and have any fixes to the slugs (if any) be put under #5034?
