(BUG) Arcane missiles not procing clearcast correctly

Here is my proof for everyone who has questioned me in other threads. My proof isn't in a vdieo or link to some ancient blizzard patch notes update, it is literally the actual talent tree tooltip. If I sound really salty in this post it is because i've contacted support through an in game page and was told that "the devs have fixed it and will be in the game soon", this was a week ago and never happened, so i was basically lied to im assuming. I messaged Daemon about it the other night and he told me to get "proof and make a thread" so here we go.
Just to clarify something about channeled spells. Each channel tick has its own individual chance to be either resisted, hit normally, or crit. It isn't like you cast a channeled spell and if it does damage the first time it will do damage every time till the channel goes away, that isnt how it works (people in other threads didnt understand that so im clarifying).
My proof :

Spells that deal channeled damage like arcane missiles and blizzard each hit targets multiple times during the spells channeling which should be procing clearcast.
The whole argument really comes down to if you have higher than elementary school reading comprehension skills or not.
