onSelected event not being called

When selecting a region on the <Plot> the onSelected event is not firing. Other events such as onUpdate and onClick work.

Plot Component:

            <Plot
                onSelected={(data) => this.setTotalData(data)}
                layout={layout}
                useResizeHandler={true}
                style={{ width: "100%", height: "100%" }}
                data={data}
            />

Function to be called:

    setTotalData = (data) => {
        console.log("Selected Data: ", data)
    }

Start with the shown usage and compare the non-working onSelected callback with the onUpdate and onClick events that reportedly work. Reproduce region selection and trace the component's event handling until the callback is invoked; done means selecting a region calls setTotalData with the selected data.
