A fix: creating or editing a marketplace listing failed whenever its description ran past 500 characters, even though the form allows 2000.
Long listing descriptions save instead of failing
The listing form accepts up to 2000 characters of description, but anything past 500 was rejected when the listing was saved, and all you saw was "Failed to create listing". The full 2000 characters now save, on both new listings and edits. A description over the limit is stopped with a message saying so, rather than a generic failure.
