I'm not entirely sure whether this can happen in d3d12, but note that
this wouldn't work for cases where the height isn't a multiple of the
block width. (Like for example the smallest mip-levels of compressed
textures. There's test_invalid_copy_texture_region(), but it doesn't
seem to test that particular case.) For comparison, see also
wined3d_format_calculate_pitch() in wined3d.
