HarmonyOS @ohos.web.webview如何设置让页面不随键盘升起被顶起

想要页面高度不随键盘变化，需要给对应的组件设置expandSafeArea。

demo：

@Entry
@Component
struct keywordExpandSafe {
  @State message: string = 'Hello World';
  @State arr:number[] = []

  aboutToAppear(): void {
    for (let index = 0; index < 14; index++) {
      this.arr.push(index)
    }
  }
  build() {
    Row() {
      Column() {
        ForEach((this.arr), (temp: number) => {
          TextInput().backgroundColor(Color.Pink)
        })
        TextInput()
        Text(this.message)
          .fontSize(50)
          .fontWeight(FontWeight.Bold)
          .onClick(() => {
          })
      }
      .width('100%')
    }
    .height('100%')
    .expandSafeArea([SafeAreaType.KEYBOARD])
  }
}
