[UI][Japanese] Mini inventory item name field shrinks to shortest viewed name, causing vertical text

Short description of the issue:
In the mini inventory with the game language set to Japanese, the item name field shrinks to the width of the shortest item name that has been viewed in Details. It never grows back, so all longer item names wrap every 1-3 characters and appear as vertical text until the game is restarted.

Steps to reproduce the issue:

1. Set the game language to Japanese.

2. Open the mini inventory.

3. Press X on the controller (Details) on an item with a 1-character Japanese name, e.g. 斧 (Axe) or 剣 (Sword).

4. Move to other items in the mini inventory.

Expected result:
The item name field width fits each item's name, and names are displayed horizontally.

Actual result:

• The name field for ALL items becomes 1 character wide, so names wrap every character and appear vertical.

• Viewing a 2- or 3-character name first shrinks the width to 2 or 3 characters in the same way.

• The width only shrinks and never grows back. Restarting the game is the only way to restore it.

• Occurs every time, in both solo and co-op.

• Does not occur in English. Switching back to Japanese reproduces it again.
