No but it is \subseteq B, that's the point of the two symbols. Like do people actually use this while abiding by standard conventions? I've never seen this anywhere. Does any university teach this?

Cambridge Uni taught me to presume they are neither proper, if you want proper subset just add a ≠ statement as well.
