Confirmed - cause found, patch not written yet.

The prepaid card is a non-equip that still carries an instance, so it renders the EQUIPMENT tooltip and prints an upgrade count of 'undefined', which also overflows the box.

Moving it out of OPEN so the list reflects reality: this one is pinned down to exact files and lines, so what is left is writing and testing the change, not working out what is wrong.

Fixed in 690f69cc.

Cause: the tooltip picked its renderer off whether the item carried an 'instance', not off what kind of item it is. Exactly one class of non-equip carries one: the prepaid cards. That is deliberate - the bag entry is a POINTER to a server-minted card row rather than a value, so a forged copy redeems for nothing. But the object only has that pointer on it: no stats, no upgrade count, no scroll count.

So hovering 'VX Prepaid - 100 points' (an ETC item) drew the full EQUIP tooltip over it: 'CATEGORY : EQUIP' because an etc item has no equip slot, six requirement rows all reading 0, every job class lit orange, and 'NUMBER OF UPGRADES AVAILABLE : undefined' printed literally.

That last line is also why the box burst its edges - at 10px it measures about 233px against a fixed 230px panel. With a real value it fits ('7' is 202px, 'None' is 221px); only the word 'undefined' overflows.

Fix: the renderer is chosen by category, so a card gets the plain ETC tooltip. Where an upgrade count is genuinely absent it reads 'None', as you asked, rather than a blank or 'undefined'.

Retest: hover a VX Prepaid card in your ETC tab.
