One of the selling points on companions was that you could Unbind and sell them. It doesn't appear you can do this.
If you drag it, it will prompt so much AD to unbind, but doesn't actually do so.
EDIT: Ingame GM confirmed it is being looked into.
Well, keep in mind that you can't sell certain Companions, like your Dire Wolf and Panther (from the Founder packs). Because you can get unlimited of them and such by just making another character.
However, as you stated, it also might be a full on bug for the ones you should be able to trade.

You don't buy and sell people like cattle. You should be ashamed of yourself.
You can already buy them, though...just not from other people. :P
