HarmonyOS 文字背景局部拉伸问题

获取文本长度的方式参考文档，让backgroundImageSize改为文字的宽度：https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-measure-V5#ZH-CN_TOPIC_0000001884917586__measuremeasuretext

实现方式demo：

import measure from '@ohos.measure'

@Entry
@Component
struct IR240513200608052 {
  @State message: string = 'Hello World啊哈哈哈哈哈哈哈哈哈';
  @State textWidth: number = measure.measureText({ textContent: this.message })

  build() {
    Column() {
      Text(this.message)
        .backgroundImage($r('app.media.startIcon'))
        .backgroundImageResizable({
          slice: {
            top: 3,
            left: 3,
            bottom: 3,
            right: 3
          }
        })
        .backgroundImageSize({ width: this.textWidth })
    }.height('100%').width('100%')
  }
}
