【报Bug】NVUE ,subNVue在子页面（非首页下）存在遮罩层丢失问题

示例代码：

showsub(){
let subNVue = uni.getSubNVueById('share');
// 打开 nvue 子窗体
subNVue.show('slide-in-left', 300, function() {
// console.log("subNVue.show")
// 在 subNVue/vue 页面触发事件
});
},
showsubmap(){
let subNVue = uni.getSubNVueById('map');
// 打开 nvue 子窗体
subNVue.show('slide-in-left', 300, function() {
// console.log("subNVue.show")
// 在 subNVue/vue 页面触发事件
});
},

},  
"uniIdRouter": {}  

}

操作步骤：

每次必现

预期结果：

subnvue只定义一次，在全部页面都能显示遮罩层

实际结果：

除首页外，为定义的subnvue页面，遮罩层丢失
