Bug report

Sometimes, there is no Base URL at the href attribution of <a></a> in markdown file after I set base in the /src/.vuepress/config.js.

Steps to reproduce

• Repo: https://github.com/itellboy/javascript-basic
• Website: https://itellboy.github.io/javascript-basic/welcome.html

I clicked 标准内建对象 or 表达式和操作符, it's right, but I clicked 语句和声明 or 函数, I got a wrong location.

What is expected?

The location in markdown file would be add Base URL that I set in base.

What is actually happening?

I have no idea how to fix it by configuration.

• Here is code
