Steps to reproduce

I've adapted the function from the README to parse markdown with strikethrough (both single & double tildes):

async function test() {

  const file = await unified()
    .use(remarkParse)
    .use(remarkGfm)
    .use(remarkRehype)
    .use(rehypeStringify)
    .process(`
## Strikethrough

~one~ or ~~two~~ tildes.
            `);

  console.log(String(file))
}

test();

Running the program does not render <del> elements:

<h2>Strikethrough</h2>
<p>~one~ or ~~two~~ tildes.</p>

Happening inside an astro project, though doubt that has an impact:

Actual behavior

The output does not include <del> elements:

<h2>Strikethrough</h2>
<p>~one~ or ~~two~~ tildes.</p>

Expected behavior

By default both single and double tildes should be rendered as del elements:

<h2>Strikethrough</h2>
<p><del>one</del> or <del>two</del> tildes.</p>

Hi Nicolas! Tests work here. So I assume that this is an Astro problem. Or you have out of date dependencies.

@wooorm thanks! I'll dig a bit deeper then and report back
