Sona's auto attack proc portion on her Q is bugged

Many times I see this happen and it looks to be completely random as to when it happens

Generally about 10% of the time, the auto attack damage portion of her Q aura does not apply for the first attack, it does it on the second for whatever reason, is especially annoying and much more noticable when you have 2 stacks of powerchord and use Q for your next auto to be empowered by the staccato powerchord but not the aura damage portion of your Q as can be clearly seen and heard by the particle and sound it resonates, often leaving you cutting off a small portion of your potential damage

pls fix
