`renderMarkdown` drops a code span nested inside `<del>`

[sandros94]

Environment

• os: Ubuntu 24
• node: v24.17.0
• pm: pnpm@11.9.0
• framework: Agnostic

Comark Version

v0.5.0

Reproduction

import { parse } from 'comark'
import { renderMarkdown } from 'comark/render'

await renderMarkdown({ frontmatter: {}, meta: {}, nodes: [['p', {}, ['del', {}, ['code', {}, 'x']]]] })
// actual:   '~~x~~'
// expected: '~~`x`~~'

await renderMarkdown({ frontmatter: {}, meta: {}, nodes: [['p', {}, ['em', {}, ['code', {}, 'x']]]] })
// '*`x`*'   ← em>code is correct

await renderMarkdown(await parse('~~`x`~~'))
// '~~x~~'

Description

The del handler returns \${textContent(node)}`, flattening children instead of recursing — so nested inline nodes are lost. em` recurses and is fine.

I'll work on a PR as soon as I'm able to
