Sortable `List`'s nested `ListInput` behavior 
Sortable `List`'s nested `ListInput` behavior 

`ListInput`'s with `sortable={false}` nested inside a sortable list were rendering the sortable handler.
This change allows `ListInput`'s sortable value to take precedence over a parent list whenever it's set, otherwise it behaves like usual.
