[GAMEPLAY] Diana's passive magic dmg doesn't proc Rylais Scepter slow. (Explanation: If intended)

Hey there,

Diana's passive ability deals magic damage at every 3rd consecutive hit. So according to the crystal scepter text the slow should apply for the reason 1: is an ability and 2: it deals dmg.

> Rylai's Crystal Scepter: Damaging spells or abilities reduce enemy movement speed by 20% for 1 second

How to reproduce:

1. Select Diana in the champion selection.
2. Buy rylai's crystal scepter
3. Attack thrice Result: No slow applied!

Reasons why it should work:

1. Teemo's E gives him passive which deals magic dmg. Rylai's effect applies - You could argue it's an ability that he can put skill points in - therefore it is handled differently
2. Fizz's passive on-hit dmg of his w also applies the Rylai's effect - you could argue they both have a dot and therefore they are treated differently.
3. Akali has a real passive that deals magic dmg (therefore comparable to Diana) and her 2nd passive proc activates the passive of Rylai's Crystal Scepter.
