It looks like you can be targeted, but you cannot target another player's target, so there's no way to utilize this for, say, cross-realm auctionhouse's

Also, the Tol Barad Tabard will not teleport you when you're under the effect of this.
You must change map ID's in your client in order to reset the glitch (or so it seems). You also cannot leave the battleground, nor join a new bg while under this effect, as the game will spit out the error "Join as group failed".
I used my tabard's that should teleport me, and it did not clear the glitch. I then hearthed, and sure enough, I'm still stuck in this mode
I'm trying to figure out a way to get it to reset at this point...
