Trade ethics restrictions may be broken on 52.03-r1

[Anticlimax17]

An elven caravan came to my fortress for trade, however, the usual ethics restrictions did not seem to apply, so I made the elves upset by trading them a lot of worn leather. The next time they arrived, I checked and found that neither the DFhack bring item to depot UI nor the trade interface show the ethics warnings as intended.
