HarmonyOS 鸿蒙Next 动态修改TextArea输入框数量时光标总是跳转到第一个输入框的问题如何避免，defaultFocus都是false

还请参考下以下demo：

import { util } from '@kit.ArkTS';

@Observed
class AcquireModel {
  public acquire: string = '';
  public id: string;

  constructor(acquire: string) {
    this.acquire = acquire;
    this.id = util.generateRandomUUID(true)
  }
}

@Entry
@Component
struct SaveImagePage {
  @State message: string = 'Hello World';
  @State @Watch('listChange') willGetList: AcquireModel[] = [new AcquireModel('')]

  listChange(v: AcquireModel[]) {
    console.log('change', JSON.stringify(v))
  }

  @State focusId: string = '';
  @State isDel: boolean = false;
  @State deleteId: string = '';

  build() {
    Row() {
      Column() {
        Text(this.message)
          .fontSize(50)
          .fontWeight(FontWeight.Bold)
        TextArea({ placeholder: '荐语' })
          .width('100%')
          .height(100)
        Text('你将获得')
        ForEach(this.willGetList, (e: AcquireModel, i: number) => {
          Column() {
            Row() {
              Child({ e: e, focusId: this.focusId, delId: this.deleteId })
              Button('-')
                .onClick(() => {
                  this.isDel = true;
                  this.deleteId = e.id
                  const index = this.willGetList.findIndex((item) => item.id === e.id);
                  console.log('indexSelf=====' + i + 'indexCom====' + index);
                  this.willGetList.splice(index, 1)
                  console.dir(this.willGetList)
                  console.log('this.focusId=====' + this.focusId)
                })
            }
          }
        }, (e: AcquireModel, i) => e.id)
        Button('+')
          .onClick(() => {
            this.willGetList.push(new AcquireModel(''))
          })
      }
      .justifyContent(FlexAlign.Center)
      .height('100%')
      .width('100%')
      .id('card')
    }
  }
}

@Component
struct Child {
  @ObjectLink e: AcquireModel;
  @Link focusId: string;
  @Link @Watch('deleteChange') delId: string;

  deleteChange(value: string) {
    if (!this.delId) {
      return;
    }
    if (this.focusId === this.e.id && this.delId !== this.focusId) {
      setTimeout(() => {
        this.getUIContext().getFocusController().requestFocus(this.focusId)
        this.delId = '';
      }, 50)
    }
  }

  build() {
    TextArea({ text: this.e.acquire })
      .layoutWeight(1)
      .height(30)
      .onChange((v) => {
        console.log(v);
        this.e.acquire = v
      })
      .onFocus(() => {
        this.focusId = this.e.id;
        console.log('now focus')
      })
      .id(this.e.id)
  }
}

此是因为数组发生了变化，ForEach刷新了UI所以焦点移动了，可以先参考下demo解决光标移动的问题
