probably possible to edit trades not being an OP

Device:
Browser: chrome
OS: win10

Steps to reproduce:
1. post a comment on a trade
2. click to edit it
i see fields and buttons for marking a trade as Sold, didn't try to do it

Anything else to add:

Thanks for this, noted. Not sure you'd actually be able to mark it sold, since it's not your trade, but you shouldn't be seeing that UI anyway.
