Import -> Image Trace -> Transparent PNG turns into gray rectangle

Hi there.
I noticed that when you upload an transparent PNG image for image trace,
the image cannot be traced. Instead the whole image is black (or gray) when importing.

Seems like the transparent color is filled with black.
Instead the transparent color should be filled with white.

I know I could open the file in an image editing tool and fill the background with white myself,
but I think it would be really useful if Easel could do this for us.

Example:

  1. Load the preview (works like it should)

  2. Import (image shows only gray)

  3. Imported in Easel it is only gray as well

Thanks for your help and keep up the great work!

Edit:
The same thing happens when I try to import an SVG
