SmartyPants: even occurrences of double quotes are not recognized

[AlekseyMartynov]

0.14.8

var p = new MarkdownPipelineBuilder()
    .UseSmartyPants()
    .Build();

var html = Markdown.ToHtml("\"aaa\" - \"bbb\" - \"ccc\" - \"ddd\"", p);

html is <p>&ldquo;aaa&rdquo; - &quot;bbb&quot; - &ldquo;ccc&rdquo; - &quot;ddd&quot;</p>

Note the alternation of ldquo-rdquo and quot-quot

I've found this too, but weirdly, it's alternating "sets" of quotes:

You spend a lot of time saying things like, “Where in
the world did all of this come from?” and "I don’t even
remember this" and “Who put this here?”

Three quoted phrases. The middle one ("I don't even remember this") retains straight quotes, while the other two have their quotes replaced.
