Volume sounds act like metronome if buttons mashed when disabling voices

The title sounds oddly specific but I couldn't reproduce this in any other way. Seems to be more consistent if it's the first song you play upon opening the game. Just pick a song, go to the chart editor, disable voices, press enter, then mash the volume keys until the time hits go, and the volume sound will keep repeating as if it was a metronome. This works on any song. Video showcasing this problem

Pretty sure this is an issue with the HaxeFlixel engine
