Hi,
Seems like line-breaks and spaces are removed, even if minify is false. See https://github.com/chialab/rna/blob/421ba5dee9cb422c1e08c8dcb44b6c83ad8b97fb/packages/esbuild-plugin-html/lib/index.js#L297C25-L297C35
Imho, better to stick to minify plugin in this case. My issue right now is that line breaks and spaces should be kept in <pre> tags...
Thanks!
