Sona's power chord randomly auto-attacking when auto-attack is disabled
I have noticed recently that sometimes when I have power chord active on Sona and I'm clicking around near minions/enemies, sometimes she will autoattack the nearest enemy as if I had auto-attack enabled. I have the auto attack option disabled in my game setttings and 99% of the time there is no issue. I have only noticed this on Sona because of how annoying it is to lose my power chord stacks to a minion, but it may just be an issue with auto-attacking. This bug is happening while using DJ Sona.
I believe it happened a few times in my last game, one for sure at 2:59: http://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/2250285563/1?tab=overview
