【报Bug】MathJax用renderjs加载后，H5可以解析，APP端报错

示例代码：

test.vue 文件

<template>  
    <view class="content">  
    {{content}}  

    </view>  
</template>  

<script>  
    export default {  
        data() {  
            return {  
                content: '解：↵首先产生了中子、质子和电子，可知最先产生的元素为氢，其中子数比质子数多1的核素，其质量数为3，核素可表示为$_{1}^{3}\textrm{H}$或T，↵故答案为：氢；$_{1}^{3}\textrm{H}$或$T$↵'  
            };  
        },  
    methods: {  
      initMathJax() {  
        console.log(MathJax)  
        // TODO:公式解析  
        MathJax.Hub.Config({

      // ...  
    }

</style>  

操作步骤：

test.vue 文件放到项目中看效果

预期结果：

test.vue 文件里的内容公式可以解析到

实际结果：

test.vue 文件在APP端报错了，报错内容为TypeError: Cannot read property 'bind' of undefined at view.umd.min.js:1
