Nidalee interaction with Predator Rune

Ok so i just played a game as and when i would use the predator enchantment as it would let me move faster and do more dmg but the problem i have with it is the fact that when i change from cougar to human form it removes the buff. Now i understand that in the description it clearly stats that any attack or ability will cancel but like ult is just a form change and it really annoys me how it just cancels so randomly. hopefully this changes but whatever :)
