Underreport a js function

[cyw3]

when i scan the file below with lizard 1.17.5, render() can not be reported.

class CanvasElement extends Component {
    render() {
        return (
            <React.Fragment>
                <div onMouseEnter={this.handleMouseEnter} onMouseLeave={this.handleMouseLeave}>
                </div>
                {this.renderHistoryBorder()}
            </React.Fragment>
        );
    }
}

output:

And when remove the line of {this.renderHistoryBorder()}:

class CanvasElement extends Component {
    render() {
        return (
            <React.Fragment>
                <div onMouseEnter={this.handleMouseEnter} onMouseLeave={this.handleMouseLeave}>
                </div>
            </React.Fragment>
        );
    }
}

output:
