Description
Example being Option, hovering None does not show size or alignment even though it doesn't depend on the generics. Feels like we should be able to show info for that? Though maybe the discriminant depends on all variants in which case we can't do anything here

Research direction
Reproduce the issue by hovering the non-generic None variant of Option and inspect the hover and layout-handling entry points involved. Determine whether layout information can be shown when the variant does not depend on generic parameters, accounting for any discriminant-related limitation; done means the hover displays size and alignment where valid.
