如果我在Chart.js画布下面添加一些东西，它会一直向上移动吗？(Angular - Chart.JS - NG2Charts)

import { Component, HostListener } from '@angular/core';

@Component({
  selector: 'app-chart',
  template: `
    <div class="chart-container">
      <canvas id="myChart"></canvas>
      <div class="other-content">其他内容</div>
    </div>
  `,
  styles: [`
    .chart-container {
      position: relative;
    }
    .other-content {
      position: absolute;
      top: 0;
      left: 0;
    }
  `]
})
export class ChartComponent {
  @HostListener('window:scroll', ['$event'])
  onScroll(event: Event) {
    // 根据滚动位置更新元素的位置
    const scrollTop = window.pageYOffset || document.documentElement.scrollTop || document.body.scrollTop || 0;
    const otherContent = document.querySelector('.other-content');
    otherContent.style.top = `${scrollTop}px`;
  }
}
