Can confirm.

This could be possible in blender as well (using materials linked to objects rather than mesh), it is just not implemented.
So this is a bit in the greyzone between request for improved behavior and bug, but since this is somewhat breaking the result in relation to what is specified in the fbx file, will confirm.
