Some logic needs to be added in "insertLlistItem" function

[meowWhat]

• I see that your list-item handles inserts at the end of the line, just adding a li

      /**
       * If end, insert a list item after and select it
       */
      const marks = Editor.marks(editor) || {}
      Transforms.insertNodes(
        editor,
        {
          type: li.type,
          children: [{ type: p.type, children: [{ text: '', ...marks }] }],
        },
        { at: nextListItemPath }
      )
      Transforms.select(editor, nextListItemPath)

This will break the parent-child relationship in the list ，like this

when insert 'break' in end of list item , The child1's father becomes parent2 from parent1

I think insert an empty node into the header of the sublist maybe better ,like this

I'm also trying to do it myself, but if the author thinks my ideas are helpful, I'll be very happy
