【报Bug】subNVues自定义导航栏，导致下拉刷新无法显示提示下拉文字提醒

示例代码：

{
"path": "pages/tabBar/home", //首頁
"meta": {
"auth": false
},
"style": {
"navigationBarTitleText": "",
"navigationBarTextStyle": "white",
"navigationStyle": "custom",
"app-plus": {
"background": "#171717",
"scrollIndicator": "none",
"titleNView": true,
"pullToRefresh": {
"support": true,
"offset": "60px",
"color": "#FFFFFF",
"style": "default",
"contentdown": {
"caption": "Pull down refresh"
},
"contentover": {
"caption": "Release refreshable"
},
"contentrefresh": {
"caption": "Refreshing"
}
},
"subNVues": [{ //导航栏
"id": "head_home",
"path": "pages/subNvues/head-home", // nvue 路径
"type": "navigationBar",
"style": { //webview style 子集，文档可暂时开放出来位置，大小相关配置
"popGesture": "none", // 组织侧滑返回, none,close
"background": "transparent",
"position": "absolute",
"top": "0px",
"left": "0px",
"width": "100%",
"height": "100%"
}
}]
}
}
},

操作步骤：

{  
            "path": "pages/tabBar/home", //首頁  
            "meta": {  
                "auth": false  
            },  
            "style": {  
                "navigationBarTitleText": "",  
                "navigationBarTextStyle": "white",  
                "navigationStyle": "custom",  
                "app-plus": {  
                    "background": "#171717",  
                    "scrollIndicator": "none",  
                    "titleNView": true,  
                    "pullToRefresh": {  
                        "support": true,  
                        "offset": "60px",  
                        "color": "#FFFFFF",  
                        "style": "default",  
                        "contentdown": {  
                            "caption": "Pull down refresh"  
                        },  
                        "contentover": {  
                            "caption": "Release refreshable"  
                        },  
                        "contentrefresh": {  
                            "caption": "Refreshing"  
                        }  
                    },  
                    "subNVues": [{ //导航栏  
                        "id": "head_home",  
                        "path": "pages/subNvues/head-home", // nvue 路径  
                        "type": "navigationBar",  
                        "style": { //webview style 子集，文档可暂时开放出来位置，大小相关配置  
                            "popGesture": "none", // 组织侧滑返回, none,close  
                            "background": "transparent",  
                            "position": "absolute",  
                            "top": "0px",  
                            "left": "0px",  
                            "width": "100%",  
                            "height": "100%"  
                        }  
                    }]  
                }  
            }  
        },
