findDOMNode was called on an unmounted component.

[ghost]

Due to debounce mechanism (function buffer), the forceAlign method may be triggered even after component was removed from DOM tree. This will result in findDOMNode was called on an unmounted component error.

The easy fix is to check if component is mounted, something like

forceAlign() {
    const props = this.props;
    if (!props.disabled && ReactDOM.isMounted(this)) {
        const source = ReactDOM.findDOMNode(this);
        props.onAlign(source, align(source, props.target(), props.align));
    }
},

but since isMounted method is deprecated, this isn't probably a best solution
