User StefCW found some of the edits, "dismissed from canon", is incorrect, like An American Tail: The Treasure of Manhattan Island for instance. According to the user, that movie is still part of the franchise's canon, but a lot were to be omitted from the next and final film. I mean there is such thing as removal by censorship, as there were a lot of political incorrectnesses, involving racism, police corruption, and worker's rights. A lot of people liked Cholena, but she and the Lenape mice were depicted as Native American stereotypes. Universal Studios withheld the movie for over year due to such concepts, fearing it would be a difficult film to market before confirming the release date. Look at Song of the South by Walt Disney from 1946. The Disney company will not release it on any home media in the North America due to the racial controversy. Even Mammy Two Shoes remains absent after the 1952 Tom and Jerry short, Push Button Kitty I just wanted to let you know according to StefCW.
