Chrome is insanely sensitive to the appearance of any hispanic-sounding last name. I find I get that in drafts any time there's a Martinez or a Juan or such atop one of the lists on the leaderboard (or in any news story that I'm reading, or pretty much anywhere else...)
On the other hand, throw a name like Borondohejweski out there and it is perfectly fine not bothering you with a translation offer. I think Chrome just wants to show off its Spanish skillz
