Fanon
While the ship is commonly focused on the Disney versions of the two, as part of the Disney Princess crossover part of the Disney fandom, there are been fans who use ship and its commonly used title with the Once Upon A Time versions of them. Which might possibly be due to Mulan being a lesbian in the OUAT series, while Elsa is believed to be one from her being a Disney Princess-Queen without a love interest; like Merida and Moana.
