Error with images in portableText

[SamMorgan]

When editing images within a text block in presentation view I get the errors: "Cannot get the leaf node at path [] because it refers to a non-leaf node ..." and/or "Uncaught Error: Cannot get the descendant node at path [] because it refers to the root editor node instead ...".

To clarify further this field schema:

    {
        name: 'text',
        title: 'Text,
        type: 'array',
        of: [
            { type: 'block' },
            { type: 'image' }
        ]
    },
