WW often used hardcoding when something was only meant for a specific useage scenario. In this case the mutation from one infantry type to another infantry type. I guess it made sense to WW to force MakeInfantry anims to use unit*.pal.
So I don't think it's a bug, it's rather a limitation.

Can't test right now, but I bet it does.
