HarmonyOS鸿蒙Next中子Window展示时是否可以保持主Window焦点状态

HarmonyOS鸿蒙Next中子Window展示时是否可以保持主Window焦点状态 由于业务需要，工程开发时希望定制键盘，且需要应用到Web页面中（不包含TextInput场景），进而考虑通过子Window展示定制键盘，用户操作后再传递到Web页面中。

在Demo测试过程中发现，假设主Window中包含TextInput，点击TextInput进入输入状态后创建子Window，当子Window展示后，主Window中的TextInput就丢失的焦点，取消了输入状态。

以上情况下，子Window展示时，是否可以保持主Window焦点状态？具体代码如下：

@Entry({ routeName: 'pages/window/WindowTestPage' })
@Component
export struct WindowTestPage {
  build() {
    Column() {
      Text('SubWindowTestPage')
    }
    .backgroundColor('#e5e5e5')
    .width('100%')
    .height('100%')
  }
}

@Entry
@Component
export struct WindowPage {
  private KeyBoardWindow: window.Window | undefined = undefined

  build() {
    List({ space: 20 }) {
      ListItem() {
        TextInput({ placeholder: '请输入内容' })
      }
      ListItem() {
        Text('创建子Window')
        .height(44)
        .width('100%')
        .textAlign(TextAlign.Center)
        .onClick(() => {
          this.createSubWindow()
        })
      }

      ListItem() {
        Text('关闭子Window')
        .height(44)
        .width('100%')
        .textAlign(TextAlign.Center)
        .onClick(() => {
          this.destroySubWindow()
        })
      }
    }
    .width('100%')
    .height('100%')
  }

  createSubWindow() {
    Single.getInstance().windowStage?.createSubWindow('WindowTestPage', (err: BusinessError, data) => {
      let errCode: number = err.code;
      if (errCode) {
        return;
      }
      this.KeyBoardWindow = data;
      const displayClass = display.getDefaultDisplaySync();
      const screenWidth = displayClass.width;
      const screenHeight = displayClass.height;

      this.KeyBoardWindow?.moveWindowTo(0, 1000, (err: BusinessError) => {
        let errCode: number = err.code;
        if (errCode) return;
        this.KeyBoardWindow?.resize(screenWidth, screenHeight - 1000, (err: BusinessError) => {
          let errCode: number = err.code;
          if (errCode) return;
          this.KeyBoardWindow?.setUIContent('pages/window/WindowTestPage', (err: BusinessError) => {
            let errCode: number = err.code;
            if (errCode) return;
            this.KeyBoardWindow?.showWindow((err: BusinessError) => {
              let errCode: number = err.code;
              if (errCode) {
                return;
              }
            });
          });
        });
      })
    }
  }

  destroySubWindow() {
    this.KeyBoardWindow?.destroyWindow()
  }
}
