According to the "HTML To Markdown for PHP" documentation,

Markdown Extra, MultiMarkdown and other variants aren't supported – just Markdown.

Which as far as I'm aware doesn't include strikethrough.

In the Elements file, I don't see it registered:

    public function isBlock()
    {
        switch ($this->getTagName()) {
            case 'blockquote':
            case 'body':
            case 'code':
            case 'div':
            case 'h1':
            case 'h2':
            case 'h3':
            case 'h4':
            case 'h5':
            case 'h6':
            case 'hr':
            case 'html':
            case 'li':
            case 'p':
            case 'ol':
            case 'ul':
                return true;
            default:
                return false;
        }
    }

I guess it would have to be added to the converter here?
