This does still happen. I hit this when trying to kill Sontalak with Archery from outside Dragon Fear range. There is enough wiggle room to fit between the edge of dragon fear and the range where this bug gets hit, but it does make it a little trickier since you won't get an out of range error and will gray out the button without attacking while moving from out of range into max range.
