Italics being applied outside content

[kokkonisd]

Hi, thank you for this work!

I've noticed an issue where text seems to be italicized outside of content, i.e. in "code" contexts:

Here, I wouldn't expect _current-slide to start an italics section, as we are in a code context (inside curly braces).

Basically, this shouldn't be producing italics:

{
    let _my_weird_variable = 42 // This shouldn't be italicized, because it's not visible markup
}

But this should:

[
    _hey!_ // This is not code, this is actual markup
]
