【报Bug】抖音小程序嵌套组件生命周期执行顺序有问题。

示例代码：

index.vue

<template>  
    <div>  
        <component-a v-bind:user-name="userName" />  
    </div>  
</template>  

<script>  
    import ComponentA from "./components/ComponentA.vue"  

    export default {  
        components: {ComponentA},  
        data() {  
            return {  
                userName: '张三'  
            }  
        }  
    }  
</script>  

ComponentA.vue

<template>  
    <div>  
        <div class="">A中直接渲染：{{studentName}}</div>  
        <component-b v-bind:user-name="studentName"/>  

    </div>  
</template>  

<script>  
    import ComponentB from "./ComponentB.vue"  

    export default {  
        components: {ComponentB},  
        props: {  
            userName: {  
                required: true  
            }  
        },  
        data() {  
            return {  
                viewReady: false,  
                studentName: this.userName  
            }  
        },  
        created(){  
            console.log("组件A created")  
        },  
        mounted(){  
            console.log("组件A mounted")  
        }  
    }  
</script>

ComponentB.vue

<template>  
    <div>组件B中渲染：{{user.name}}</div>  
</template>  

<script>  
    export default {  
        props: {  
            userName: {  
                required: true  
            }  
        },  
        data() {  
            return {  
                user:{  
                    name:this.userName  
                }  
            }  
        },  
        created(){  
            console.log("组件B created")  
        },  
        mounted(){  
            console.log("组件B mounted")  
        }  
    }  
</script>

操作步骤：

下载附件中的代码直接运行即可。

预期结果：

预期打印顺序为：
组件A created
组件B created
组件B mounted
组件A mounted

实际结果：

实际打印顺序为
组件A created
组件A mounted
组件B created
组件B mounted
