How to link to a title in the same document by MathJax `\href`?

I know we can create a link by `\href` with MathJax.

```tex
$$
\href{https://this.is.a.doc/}{\text{this is a doc}}
$$
```

However, it seems that `\href` only works when the link starts with `http(s)://`. I want to link to a title in the same document.

```tex
$$
\href{#the-title-in-the-same-document}{=}
$$
```

Is it possible?
