[Gameplay] Guardian Angel Cooldown Bugged

I've had this happen in multiple games now, and after seeing it on a Cowsep video (link, at timestamp 1:46) yesterday I realized this is a pretty big bug.

For summoners who take Perfect Timing and/or Cosmic Insight, they visually reduce the cooldown of Guardian Angel in your inventory, but you don't acquire the animation around your character at the 4 minute mark, and it remains on a 5 minute cooldown.

In other words, it appears that your GA is up if you look at the item in your inventory (and it should be), but in reality it isn't.

This has lead to me, some friends, and even streamers such as Cowsep making plays we otherwise wouldn't, thinking that Guardian Angel is available, and only realizing afterwards that it isn't.

Please upvote for relevance and submit a bug report yourselves if possible, this is a considerable bug. Thank you!

Edit: Very easy too test, just go into a practice game with Perfect Timing and Cosmic insight, kill yourself in the enemy fountain after buying a GA fast, and skip the time ahead too where it's visually off cooldown in inventory, before killing yourself again.

Alternatively, do it in a real game, for worse results.
