Just to chime in...the intention of the hand in question was not to be a salute (since her gesture is not being done with an official salute hand/arm) but more of a gesture of a 'hiya' or 'Seeya'. The concern about it being taken as a salute gesture has been heard though and it's currently being evaluated and looked at for modification to make it look less salute like.

And before anyone asks...I do not know if the portrait will be changed. I've only been made aware of salute-gate 2015. :-)
