[CLIENT] Spectator Mode has Incorrect Cooldown Indicators on Champions' Icons

Next to the champions' icons in the spectator mode, the cooldown indicators for their ultimates and summoner spells used to be correct. Starting in 8.5, this particular cooldown indicator is almost always wrong each time I spectate someone. The cooldowns in the box on the bottom-left of the screen when I click on a champion is still correct.

This can be reproduced by spectating anybody. However, I'm not sure if it's only happening on my client or with other people. I've attached a screenshot of the issue - Twisted Fate's cooldowns are clearly out of sync.
