I'm sure this question has come up before but I haven't been able to find a solid answer.
Would a cone shaped burst spell, like cone of cold, become a 120 ft. cone when you apply Widen Spell to it? It seems like the increase to 120 ft. would add more than double the spell's area, as described in the feat description. And as far as I can tell, since the spell is a burst, it would be affected by the feat.
