HarmonyOS progress组件线性样式设置渐变色不生效，是dp2版本API暂不支持吗

Progress({ value: 70, total: 100, type: ProgressType.Linear }) 
  .width(100) 
  .height(9) 
  .margin({ right: 16 }) 
  .color( new LinearGradient([{ color: "#65ed08f5", offset: 0 }, { color: "#65ef0849", offset: 1 }])) 
  .alignRules({ 
    'top': { anchor: "__container__", 'align': VerticalAlign.Top }, 
    'right': { anchor: "netWorkStateImage", 'align': HorizontalAlign.Start }, 
    'bottom': { anchor: "__container__", 'align': VerticalAlign.Bottom } 
  }) 
  .backgroundColor($r('app.color.rb_v1_timer_bg')) 
  .id('timeProgress')
