I can't agree with that James, as someone who has run a server with this bug for a few snapshots and experienced all the cases of this. I don't believe they are caused by eachother. I managed to fix the portal loop using commands that would detect a change in dimension and move you away from the portal, after you're free from the portal it would still teleport you to your last coordinates in the dimension you're currently in (not everytime). It would NOT bring you back into the portal and teleport again, leading me to believe they are unrelated.
