The Termbox v2 / mobile termbox is still displaying the anonymous edit warning that mentions the user's IP address, even when TempUser is enabled. Update the Anonymous Edit warning so that it does not reference the user's IP address if TempUser is enabled on the Repo.
To reproduce the issue, switch to mobile view (by clicking the "Mobile view" link in the page footer) and make an edit while logged-out on a wikibase repo that has tempuser enabled.
