She’s got a Russian name and western features, so I’m guessing she’s not ethnically a Kazakh. About 25% of Kazakhstan’s population are Russians, and they don’t like the Kazakhs very much (feeling is mutual) so if she knew it was the wrong anthem it may have amused rather than enraged her.
A large proportion of the ethnic Russians in that country are descended from former Gulag prisoners who when released in the 50’s were “exiled” to the area near their last camp. And strangely quite a few are descended from former camp guards who chose to retire there. There are a large number of Russian Kazaks in the New York City area although many are illegals.
