HarmonyOS CustomDialogController与Navigation冲突

想在Component层弹出对话框，可以采用stack堆叠的方式控制隐私弹框的显隐。

具体请参考以下代码：

@State privacyShow:boolean = true
build() {
  Navigation(this.appPathStack) {
    Column() {
      Stack(){
        Text('Splash Page')
          .fontSize(50)
          .fontWeight(FontWeight.Bold)
        if(this.privacyShow){
          Column(){

          }.width('100%').height('100%').backgroundColor(Color.Gray).opacity(0.1)
          PrivacyDialog({
            onPrivacyClick: async () => {
              this.appPathStack.pushPath({
                name: 'privacy',
              });
            },
            onAgreementClick: async () => {
              this.appPathStack.pushPath({
                name: 'privacy',
              });
            },
            onAgree: () => {
              this.privacyShow = false
            },
            onRefuse: () => {
              this.exitApp();
            }
          })
        }else {

        }
      }

    }
    .width('100%')
  }
  .hideTitleBar(true)
  .navDestination(this.appRouter)
  .mode(NavigationMode.Stack)
}
