HarmonyOS 自定义底部弹窗 (CustomDialog)无法设置四角圆角

参考示例：

import { ComponentContent, window } from '@kit.ArkUI';
import { BusinessError } from '@kit.BasicServicesKit';

@Builder
function buildText() {
  Column() {
    Text("这是一个弹框")
      .fontSize(20)
  }
  .width('100%')
  .height(200)
  .backgroundColor(Color.Red)
  .borderRadius({
    topLeft: 10,
    topRight: 10,
    bottomLeft: 40,
    bottomRight: 40
  })
}

@Entry
@Component
struct Parent {
  build() {
    Column() {
      Column() {
        Button("click").onClick(() => {
          let uiContext = this.getUIContext();
          let promptAction = uiContext.getPromptAction();
          let contentNode = new ComponentContent((uiContext as UIContext), wrapBuilder(buildText));
          try {
            promptAction.openCustomDialog(contentNode, {
              isModal: false,
            });
          } catch (error) {
            let message = (error as BusinessError).message;
            let code = (error as BusinessError).code;
            console.error(`OpenCustomDialog args error code is ${code}, message is ${message}`);
          }
          ;
        })
      }
    }
  }
}
