HarmonyOS 自定义Dialog高度问题

示例如下：

@CustomDialog
struct CustomDialogExample {
  cancel?: () => void
  confirm?: () => void
  controller: CustomDialogController

  build() {
    Column() {
      Text('我是内容').fontSize(20).margin({ top: 10, bottom: 10 })
    }.height('100%')
  }
}

@Entry
@Component
struct CustomDialogUser {
  dialogController: CustomDialogController = new CustomDialogController({
    builder: CustomDialogExample({
      cancel: ()=> { this.onCancel() },
      confirm: ()=> { this.onAccept() },
    }),
    alignment: DialogAlignment.Center,
    autoCancel: true,
    customStyle: true
  })

  onCancel() {
    console.info('Callback when the first button is clicked')
  }

  onAccept() {
    console.info('Callback when the second button is clicked')
  }

  build() {
    Column() {
      Button('click me')
        .onClick(() => {
          this.dialogController.open()
        })
    }.width('100%').height('100%')
  }
}
