Renaming items by anvil increases the prior work penalty

^{Update by} @unknown^:
Summary:
Renaming an item using an anvil increases the prior work penalty, it should not.  It should only add a single level, plus any prior penalty.
 
Wiki:
Renaming always costs a single level, in addition to any Prior Work penalty. Renaming will not increase the prior work penalty.

Repro Steps:

1. Obtain sufficient XP

2. Switch to Survival

3. Rename a new sword in an anvil

4. Notice the XP cost

5. Rename it several more times, and notice the exponential increase in cost

Observed Results:
The costs doubles each time it's renamed. In Survival, the item will become 'too expensive'  to upgrade, rename, or repair.

Expected Results:
Renaming should only cost one level each time, and should not add to the prior work penalty.
