Steps to reproduce

读取某一篇md报错 其他的正常 应该是某个格式和vue解析的时候冲突了

What is expected?

希望改进这个问题

What is actually happening?

当我正常的加载md文档的时候，出现以下的报错，我理解我的md文档应该可以写任意内容啊，为什么要限制呢 如果这样的话岂不是很不灵活

报错信息如下：
runtime-dom.esm-bundler.js:593 Uncaught (in promise) DOMException: Failed to execute 'setAttribute' on 'Element': '5' is not a valid attribute name.

I think this is not the right place to report an issue.
