Yes! I just watched it. It was really interesting to see the differences between it and the full-length movie - like they went a different direction with the mother in the movie; in the trailer she's more of a generic concerned mother. And the things that didn't carry over - like the part near the end with the girls skating around in dresses, particularly the two in those matching blue and white floating robes.

But there's a dream-like quality to the short (particularly the way the girls show up, like magic, after our heroine takes a fall), which makes that fit in there when it would have fit less well in the movie.
