How to reproduce Hover over the line so the Tooltip shows near the title of the chart

Additional context It looks like an easy fix could be to construct the Tooltip after the title is added. So the Tooltip is after the title in the DOM and shows above it.

Instead of having the New Tooltip in the constructor, you could put it in the render: src/Line.js

  render() {
    if (this.title) addLabels.title(this.svgEl, this.title);

    this.tooltip = new Tooltip({
      parent: this.svgEl,
      title: '',
      items: [{ color: 'red', text: 'weweyang' }, { color: 'blue', text: 'timqian' }],
      position: { x: 60, y: 60, type: config.positionType.dowfnRight },
      unxkcdify: this.options.unxkcdify,
    });
