Speaking of that painting with Iduna, you can see really young Elsa wearing gloves.

Maybe Elsa was unable to control her power due to her loneliness and lack of love from her parents. That's why they made Anna hoping that it would solve the problem (which it did). Anna didn't get any act of love either considering that she had her stream of white hair even after the death of her parents and it would have disappeared with any act of love like it did at the end of the movie.
