When I have the following code block:

var pipe = new EventPipe(document, 'keydown', function(evt) {
    pipe.send(evt);
});

Markdox produces markdown with the single quotes changed to '
And since the this markdown is placed in a <pre><code>...</code></pre> block when the .md file is included in an HTML page using the markdownify plugin in Jekyll, the ' is seen in the final output:

var pipe = new EventPipe(document, `'`keydown`'` function(evt) {
    pipe.send(evt);
});

I'm using Markdox via the grunt-markdox task: https://npmjs.org/package/grunt-markdox

Why does Markdox change quotes and double quotes?
