Origin of the "Matroyshka" transposition error?

Hello Everyone! I have been studying Russian formally for two semesters, now, having plenty of fun and learning a great deal, but some things remain mysterious.

For us in the west, there is a sporadic sprinkling of communities where English speakers seem to have randomly begun calling matryoshka/матрёшка as "matroyshka" as if the city of Troy were the theme of the doll. It is very intriguing to me, because I grew up around many Russian heritage speakers, but I coincidentally never heard them speak of the dolls in any context. Others from outside the culture were always calling them "matroyshka dolls" and I even found this news broadcast that helped me to recognize that I was not hallucinating this effect!

Alas, documentation of this effect and where it seems to have stemmed from appears to be a mystery, with searches online not revealing much to me. Perhaps some of you know more? Even if not, it is interesting, no? Thank you for your time!
