Crashing & Incorrect display math rendering inside blockquotes

[nfbyte]

Summary 1

(I'm using the GitLab delimiters setting)
The following code crashes the mdmath extension (similar to #50):

>```math
blabla
```

Summary 2

Also, display math inside blockquotes is not rendered properly in the VSCode preview.

Expected behavior

>```math
>\frac{1}{2}
>```

and

> ```math
> \frac{1}{2}
> ```

should render to:

inside a blockquote.

Actual behavior

>```math
>\frac{1}{2}
>```

doesn't render at all, and

> ```math
> \frac{1}{2}
> ```

renders to:

inside a blockquote.

Environment

     Operating system: Windows 10 64bit
       VSCode version: 1.44.2
Markdown+Math version: 2.4.0

yes ... I was able to reproduce that bug. In fact it was independent of the rules set.

With new Version 2.5 please test it, I already did it and the bug should be resolved now.

Please note, that with multiline display formulas in blockquote blocks you need to start each new (formula) line with a > character, as in

>```math
>\frac{1}{2}
>```

A whitespace character is allowed but not needed after the > character. Multilevel blockquote blocks are also supported now.

You can also write your formula on a single line, as in

> ```math \frac{1}{2} ```

thanks
