Steps to reproduce

const myChart = echarts.init(document.getElementById('main'));
        const option = {
            xAxis: {
                type: 'value',
            },
            yAxis: {
                type: 'value',
            },
            series: [
                {
                    type: 'custom',
                    data: [[1, 2]],
                    renderItem(params, api) {
                        return {
                            type: 'rect',
                            shape: {
                                x: 100,
                                y: 100,
                                width: 100,
                                height: 100,
                            },
                            info: { a: '23' },
                            style: {
                                fill: 'red',
                            },
                        }
                    }
                }
            ]
        }
        myChart.setOption(option);
        myChart.on('click', params => {
            console.log(params.info);//When i click the rect,i get undefined.
        })

What is expected?

series-custom.renderItem.return_rect.info;
console:{ a: '23' }

What is actually happening?

params.info is undefined;
The same as others.(group,circle and so on.)
