How is it that Nestorius is venerated in the Syro-Malabar Catholic Church?

In a sense, related to https://christianity.stackexchange.com/questions/96803/what-is-the-controversy-that-is-leading-the-syro-malabar-catholics-into-schism See [Wikipedia: Nestorius](https://en.wikipedia.org/wiki/Nestorius) and observe the churches that venerate Nestorius. How is it that Nestorius is venerated (presumably as a Saint) in the Syro-Malabar Catholic Church when the Catholic Church had formally condemned Nestorius as a heretic at the Ecumenical Council of Ephesus in the fifth century? Is this possible?? Could there be a mistake here?
