Mathjax makes the closest bullet point disappears

For example I have a markdown file:
```md
1. First point
2. Second point
3. Third point
4. Fourth point
$$
y=ax+b
$$
5. Fifth point
```

> What I expected to see:
> 

> What actually rendered:
> 

I've tried different combinations of indentation and I find out that this markdown renders what I expected:
```md
1. First point
2. Second point
3. Third point
4. Fourth point
4.
$$
y=ax+b
$$
5. Fifth point
```

Reproduce the issue with the numbered-list Markdown example and compare the expected and actual screenshots. Start by locating the Markdown/MathJax rendering entry point, then verify the fix by confirming the list item remains visible when the indented display equation is present and add a regression test if the project has a relevant test area.
