It a disney movie, usually there is a princess rescued by a prince. Here we just have two princess who go rescue each other and in the end it's the true love of Elsa that save Anna.
Elsa and Anna take turn being the prince and there is the true love thing. That's what make people think of this pairing I think.
Edit : There is also the way they compliment each other at the beginning
