no hitsounds if pressed key overlaps

[arily]

my setup:
I am using "," and "." for left and right click, have alternating playstyle.

I noticed that if I keep holding the first key while press other key to hit next object there's very high chance that no hitsound will be played.
Doing further investigation I found out that if the previous object is a "note", doing what I described will resolve to no hitsound.
