Yasuo bug.

So, with the new changes to crit items, I decided to try something on Yasuo. I got a IE first + Brawler's Gloves. BG grant 10% crit chance on their own, so with Yasuo passive and IE passive, this should go to 40%. But it only stayed at 20% and the number wouldn't change, no matter how many times I would sell and rebuy the item etc.

Buying a Zeal (15% chance) correctly increased by crit chance to 60% though. Therefore, the bug only seems to exist for BG. I'm not saying rushing IE is good or anything on Yasuo at least, but maybe spending 4300 gold to get 60% crit alongside the true damage and 80AD from IE would be an idea to consider.
