Quick Cast Indicators Won't go Away Post Cast

Now if you spam an ability over and over while quick casting with indicators, the indicator stays after casting the ability, making you unable to cast more abilities until you right click to cancel the indicator of an ability you already used. Stop messing with quick cast please Riot. I experienced this with Annie's Q, W, and R, and master Yi's Q, so I assume it extends to all champions. I'm on a mac if that matters.

• It's not from spamming. The bug happens when you press a button to cast an ability, and then hold down the button again for X seconds during the cast time (can be like, < 0.5 seconds).

• It is always reproduced by casting an ability, and then pressing and holding the button for that ability again for the full duration of the cast time. After releasing the button, the indicator persists.

• But it doesn't have to be the full duration, it seems to occur earlier on some abilities.

• It also isn't just abilities. It affects targeted summoner spells (Ignite, Teleport, Smite) and sometimes, the range indicator dissapears but the blue diamond targeting indicator doesn't dissapear, and it goes away randomly after right clicking minions several times. You're also unable to left click the minimap while your cursor is stuck as a targeting indicator.

• All of these bugs go away when you turn off quick cast with indicator. But if it's bugged, then why is it even a feature?

STOP MESSING WITH QUICK CAST WITH INDICATOR AND FIX IT RIOT!!!!
