customizing with trackXRenderer doesn't work because elementRef is missing in props

[nathanbamford2]

Hi, this is a great tool, but I can't seem to figure out how to make the custom render for trackX work. When I get the props like in the example:
trackXRenderer={ props => { const {elementRef, ...restProps} = props; return <span {...restProps} className="MyAwesomeTrackVertical" ref={elementRef}/> } }
props only has children, className, onClick, and style, with no elementRef. As a result the scroll doesn't function.

When I look in the code under dist/Track.js, I see this:
props = _objectWithoutProperties(_this$props, ["className", "renderer", "type", "elementRef", "onClick"]); props.className = "track " + (type === TYPE_X ? "trackX" : "trackY") + (className ? " " + className : ""); props.onClick = this.onClickHandler; return renderer ? renderer(props) : _react.default.createElement("div", _extends({}, props, {

It's clearly stripping out the elementRef property before calling my custom render function.

Is this by design? Am I meant to somehow implement the custom render without the elementRef property?

Thanks,

Nathan
