React-admin: Warning: React does not recognize the `fullWidth` prop on a DOM element.

[idocal]

What you were expecting:
Show view should have compiled with no warnings.

What happened instead:
The warning keeps appearing.

Steps to reproduce:

1. Create a new Show with either TabbedShowLayout or SimpleShowLayout.
2. Create any TextField

Related code:

export const PresetShow = (props) => (
    <Show {...props}>
        <TabbedShowLayout>
            <Tab label="content">
                <TextField source="content" />
            </Tab>
            <Tab label="summary">
                <TextField source="id" />
                <TextField source="title" />
                <TextField source="language" />
                <TextField source="category" />
                <DateField source="date" label="Published at" />
            </Tab>
        </TabbedShowLayout>
    </Show>
);

This warning still exists when using something as simple as:

<Show>
    <SimpleShowLayout>
        <TextField source="title" />
    </SimpleShowLayout>
</Show>

Yes, because the fix has not been released yet. It will be 2.0.4

What must I do here? It was working before without error.
