Very simple preformatted code block does not get converted properly

[dddoyle1]

I have a very simple element:

<pre>
<code class="">
fruits = ["apple", "banana", "cherry"]

for fruit in fruits:
  print(fruit)
</code>
</pre>

that I would like converted to a fenced code block via TurndownService::turndown

I initialize the TurndownService with

var turndownService = new TurndowSnService({codeBlockStyle: "fenced"});

However, turndown yields the following string when I pass my element:

"fruits = [\"apple\", \"banana\", \"cherry\"]\n\nfor fruit in fruits:\n  print(fruit)"

I've verified by hand that the fencedCodeBlock.filter returns true when passed my element and that fencedCodeBlock.replacement returns the expected string sandwiched by the fence, but this behavior is not reproduced as expected when using TurndownService::turndown

This looks like it's working on the live demo: https://mixmark-io.github.io/turndown/ The output is:

```

fruits = ["apple", "banana", "cherry"]

for fruit in fruits:
  print(fruit)
```

Looks like this happens only when I pass the HTML element directly, whereas if I instead do

turndownService.turndown(element.outerHTML)

the element is converted as I expected. Is this intended behavior?

FWIW, I see that when I pass the element directly, the thing that makes it to fencedCodeBlock.filter is a node with "\

...\

" stripped away, ie a code node, which fails the filter criteria

The codeBlockStyle option will do this for you. For example:

var turndownService = new TurndownService({ codeBlockStyle: 'fenced' })
turndownService.turndown('<pre><code class="language-js">console.log("hello world")</code></pre>')
