How would Russians view a non-Russian ruler?

We know that throughout its history Russia has had well known leaders who were of non-Russian ethnicity, chief amongst them being Catherine II and Joseph Stalin. Granted, during Catherine’s time the notion of a nation state wasn’t fully matured yet and she married into the royal family thereby adopting into the Russian culture, and in case of Stalin it was during the USSR which put an emphasis on the collective ethnicities living under one leadership and thus more open to non-Russian ethnic minorities from ruling over this collective state. With all of this bearing in mind, during history classes are the foreign nationalities of such leaders mentioned in schools? Consequently how accepting would modern Russia be towards non-Russian ethnicities ruling over them?
