Nested Razor blocks breaks formatting

[nwoolls]

Hi there - first and foremost thanks for the grammar!

I am finding that nested blocks of Razor break the formatting. Specifically I am using the following to illustrate this:

<markdown>
    ```cshtml
    @@if (this)
    {
        <span>this</span>
        @@if (this)
        {
            <span>this</span>
        }
        else if (that)
        {
            <span>that</span>
        }
        else {
            <span>nope</span>
        }
    }
    else if (that)
    {
        <span>that</span>
        @@if (this)
        {
            <span>this</span>
        }
        else if (that)
        {
            <span>that</span>
        }
        else {
            <span>nope</span>
        }
    }
    else {
        <span>nope</span>
        @@if (this)
        {
            <span>this</span>
        }
        else if (that)
        {
            <span>that</span>
        }
        else {
            <span>nope</span>
        }
    }
    ```
</markdown>

This results in the following HTML:

Specifically, note the instances of e.g. }, else if (that), {, and else { that have no surrounding HTML tags.

This ends up rendering (with the GitHub Dark theme) as such:
