Also it says that we will be seeing the Stepsisters. With an ‘S’ on the end making it plural meaning both of them. So that means that either they’ve recast Ana (they did it with Jafar so I wouldn’t put it past them), they’re completely just ignoring Wonderland or they’ve got Anna Rigby back and managed to keep it under wraps.
There is the option that there are more than two stepsisters, which would match with how Anastasia’s mother said “At least I have your sisters”. I’m not sure if she would have counted Cinderella, knowing how Lady Tremaine treats her. I’m thinking they’re going to completely ignore what they seemingly hinted on Wonderland, and act like that was never their plan.
