the "\begin{cases}" can not work in vuepress

[lvmengtian]

Hello，I am using vuepress-plugin-mathjax in vuepress. Now some problems troubles me.

Content in markdown is

$$f(i>>1)=\begin{cases}f(i)& \text{i的最后一位是0}\\f(i)-1& \text{i的最后一位是1}\end{cases}$$

After building and devloping the vuepress，It doesn't work.

But it is works in https://www.mathjax.org/#demo。

One solution is change the dependencies "mathjax3": "3.0.0-beta.3" to "mathjax-full": "^3.1.4", and change the file "src/tex2html" like this.
But this way can only support svg because in 3.14 is another way to deal with chtml. I'm not good at vue nor node, maybe someone can solve it.
