HarmonyOS textarea组件设置maxlength的时候,当输入到最大长度的时候,框框会红,能不能去掉

@Entry  
@Component  
struct TextAreaDemo {  
  @State message: string = 'Hello World';  
  build() {  
    Row() {  
      Column() {  
        Text(this.message)  
          .fontSize(50)  
          .fontWeight(FontWeight.Bold)  
        TextArea().width('80%').height('15%').maxLength(5)  
          .showCounter(true, { highlightBorder: false })  
      }  
      .width('100%')  
    }  
    .height('100%')  
  }  
}
