HarmonyOS 调用bindPopup内嵌图片时，图片外包含气泡阴影无法消除

.bindPopup(this.showPopup, {  
          builder: this.CapaBubble,  
          placement: Placement.Top,  
          mask: false,  
          backgroundBlurStyle: BlurStyle.NONE,  
          showInSubWindow: false,  
          enableArrow: false,  
          radius: 8,  
          shadow: {  
            radius: 0  
          },  
          onStateChange: (e) => {  
            if(!e.isVisible) {  
              this.showPopup = false  
            }  
          }
