Typing in "snow mexican" to the address bar of Safari surfaces a Wikipedia result, which shows up as "Snow Mexicans (Inuit)" and points to the "Inuit" article. As far as I can tell, there is not and has never been a redirect like that on Wikipedia itself — if there was, it's been oversighted.
The person who reported it to me also gets that result on desktop Safari just from typing in "Inuit":
Obviously, this reflects poorly on Wikipedia. Is this something completely on Apple's side, or is this some legacy of cached vandalism, or what?
