Uncaught Error: Unable to find node on an unmounted component.

React and React-DOM versions are both ^16.6.0. (according to my package.json) I am well aware that this error message often arises due to React/React-DOM version mismatches but that doesn't seem to be the case here?

I have a blue/red slider I modified from the rc-slider@8.6.3 examples.

The slider is inserted into my react component, however I if I try to move it I get Uncaught Error: Unable to find node on an unmounted component.

I've cut out my code and built a bare component with the slider. It still renders perfectly but still produces the same error when you try to move it:

class LeftSidebar extends React.Component {

    constructor(props) {
        super(props);
        this.state = {
            malePercentage: 50
        };
        this.onSliderChange = this.onSliderChange.bind(this);
    }

    onSliderChange(value) {
        this.setState({ malePercentage: value })
    }

    render() {
        return (
            <div>
                <Slider
                    min={0} max={100}
                    defaultValue={50}
                    trackStyle={{ backgroundColor: 'blue', height: 10 }}
                    handleStyle={{
                        borderColor: 'green',
                        height: 28,
                        width: 28,
                        marginLeft: -14,
                        marginTop: -9,
                        backgroundColor: '#00bc66',
                    }}
                    railStyle={{ backgroundColor: 'red', height: 10 }}
                    value={this.state.malePercentage}
                    tipFormatter={value => `${value / 10}:${(100 - value) / 10}`} //display M:F ratio
                    onChange={value => this.onSliderChange(value)}
                />
            </div>
        );
    }
}

export default LeftSidebar;

Am I missing something trivial? I've lost track of how many desperate nonsensical little changes I've made to try and make it work

Start with the package.json versions and the minimal LeftSidebar reproduction using rc-slider@8.6.3 and the React/React-DOM ^16.6.0 pair. Reproduce the error by moving the controlled slider, then compare the setup with the linked rc-slider examples; done means moving the slider no longer reports an unmounted component.
