Feedback Normal Map texture in sprite editor

Normal Map texture in sprite editor appears as transparent pink.

Which is not a big deal, since normally it is just a secondary texture, but still... I think this should be improved to show the normal looking the same as in the project view. with proper blueish tint.

Also, if it is properly displayed it can help on some occasion where if sprite is small, the sprite editor can show as zoomed in to help visualize better.

having transparent pink look for normal map is just not good for both visual wise and productivity wise

Maybe it is looking like that to distinguish between real sprite and normal map?
