Nativescript后退按钮不会重定向到正确的页面

我正在尝试为Android创建一个Angular 2组件，用于显示特定 path 的内容 . 为此，我创建了以下app-routing.module：

@NgModule({
  imports: [
    NativeScriptRouterModule.forRoot([
      { path: '', component: HomeComponent },
      { path: 'folder-content/:path', component: FolderContentComponent },

    ])
  ],
  exports: [NativeScriptRouterModule]
})

为了完整性，这里是folder-content.xml的xml

<StackLayout>
    <GridLayout row="auto, *" row="2">
        <ListView [items]="getContent(currentPath)">
            <template let-item="item">
                <GridLayout columns="auto, *"   [nsRouterLink]="['/folder-content', item.path]">
                    <GridLayout columns="auto" rows="auto" cssClass="favorite-wrap">
                        <Image id="imgFav" [src]="item.isFile() ? 'res://ic_add_to_fav_1': 'res://folder'" stretch = "none" cssClass="icon-image"></Image>
                    </GridLayout>
                    <StackLayout col="1">
                        <Label [text]="item.name" cssClass="info-bigger"></Label>
                        <Label [text]="item.path" cssClass="info-orange"></Label>
                    </StackLayout>
                </GridLayout>
            </template>
        </ListView>
    </GridLayout>
</StackLayout>

每次点击列表项时，我都想导航到同一页面，但是使用不同的参数（这可以按预期工作） .

问题是当我尝试向后导航（使用物理后退按钮）时，我被重定向到HomeComponent而不是FolderContentComponent .

我尝试使用以下代码段打印路由器事件以获取更多信息：

router.events.forEach((event) => {
     console.log(event);
    });

从 the default path 导航到 folder-content +'/' 作为参数时，我得到以下内容：

JS: NavigationStart(id: 19, url: '/folder-content/%2F')
JS: RoutesRecognized(id: 19, url: '/folder-content/%2F', urlAfterRedirects: '/folder-content/%2F', state: Route(url:'', path:'') { Route(url:'folder-content/%2F', path:'folder-content/:path') } )
JS: NavigationEnd(id: 19, url: '/folder-content/%2F', urlAfterRedirects: '/folder-content/%2F')

从 folder-content +'/' 导航到 folder-content +'/sdcard': 时，我得到以下信息

JS: NavigationStart(id: 20, url: '/folder-content/%2Fsdcard')
JS: RoutesRecognized(id: 20, url: '/folder-content/%2Fsdcard', urlAfterRedirects: '/folder-content/%2Fsdcard', state: Route(url:'', path:'') { Route(url:'folder-content/%2Fsdcard', path:'folder-content/:path') } )
JS: NavigationEnd(id: 20, url: '/folder-content/%2Fsdcard', urlAfterRedirects: '/folder-content/%2Fsdcard')

但是，当按下后退按钮时，我希望从f older-content +'/sdcard' 导航到 folder-content + '/' ，但我会被重定向到''（HomeComponent）

JS: NavigationStart(id: 21, url: '/')
JS: RoutesRecognized(id: 21, url: '/', urlAfterRedirects: '/', state: Route(url:'', path:'') { Route(url:'', path:'') } )
JS: NavigationEnd(id: 21, url: '/', urlAfterRedirects: '/')

重要的是要提到我使用 page-router-outlet 而不是标准的Angular路由器 .
