I was bothered by the null chaining here. We know we have a sort item, so I updated types to reflect that.

I also thought that your logic was a bit hard to follow. And it is by chance that the sort selection order is asc -> desc -> null. I think this could be flipped around separately. So I think what I have is more clear on what we are actually doing and ensure we flip the order correctly regardless of grid configuration.

What do you think?

I like that approach, I was fighting the optional chaining. LGTM
