ReferenceManyField fullWidth only works when addLabel={false}

[davidhenley]

Is NOT full width

        <ReferenceManyField ... fullWidth>
          <Datagrid>
            <TextField source="id"/>
            <DateField source="orderDate"/>
            <DateField source="shipDate"/>
          </Datagrid>
        </ReferenceManyField>

Is full width

        <ReferenceManyField ... fullWidth addLabel={false}>
          <Datagrid>
            <TextField source="id"/>
            <DateField source="orderDate"/>
            <DateField source="shipDate"/>
          </Datagrid>
        </ReferenceManyField>
