1. Fixed.
2. If size of the icon based checkbox/radio button is less or equal than the icon size then the central part of the icon will be cropped and the halo will not be visible unless there are transparent pixels in the icon or icon is procedural and not paints on the whole icon area. We will not draw over other components in this case.
