Autoattacking a plant should NOT use up Sona's Power Chord

As a level 7 Sona main, this drives me nuts. Why does auto-attacking a plant with Power Chord active consume the Power Chord? Auto-attacking a ward does not consume the Power Chord, so why are plants different? I know this is just a minor thing, but I would appreciate if this change was considered.
