Material-UI CSS not injected

[saraivinha85]

Describe the bug
Material-UI CSS not injected when components are rendered after first mount.

To reproduce
Working code:

render() {
        const buttons = ['Hello'].map((p) => <Button variant="contained" color="primary" key={p}>p</Button>)

        return (
            <div style={styles.root} > 
                {buttons}
            </div>
        )
    }

Not working code (labels are injected later using redux):

render() {
            const { labels = [] } = this.props.labels
        const buttons = labels.map((p) => <Button variant="contained" color="primary" key={p}>p</Button>)

        return (
            <div style={styles.root} > 
                    {buttons}
            </div>
        )
    }

Expected behavior
The buttons should appear styled.
