Yep sure enough. I tested this to see what was happening. It doesn't look like the UI is setting correct icon sizes just correct background size. So it would be up to tknarr or Silat or even gm9 to find that and correct it.
It doesn't do this changing the normal beneficial or determental sizes so it must be something in the target window. I didn't test the implied though might do that and see if that appears there as well.
