Steps to reproduce
> mkdir repro && cd repro
> npm init
> npm i "hast-util-from-html" "hast-util-raw" "hast-util-to-html"
> editor index.mjs # Paste contents from below
> node index.mjs// index.mjs
import { fromHtml } from "hast-util-from-html";
import { raw } from "hast-util-raw";
import { toHtml } from "hast-util-to-html";
const contents = `<table>
<thead>
<tr><th>Column</th></tr>
</thead>
<tbody>
<tr><td>foo</td></tr>
<tr><td>bar</td></tr>
</tbody>
</table>`;
const hast = fromHtml(contents, { fragment: true });
const reformatted = raw(hast);
console.log("Without util-raw:");
console.log(toHtml(hast));
console.log("With util-raw:");
console.log(toHtml(reformatted));Expected behavior
hast-util-raw shouldn't add whitespace lines at the start.
This was discussed in rehypejs/rehype-raw#22 and they decided it wasn't a bug since ordinarily browsers parse it the same, however, when using non-default values of the CSS property white-space (such as pre or pre-wrap) this issue appears.
Actual behavior
A text node with whitespace is added:
{
// ...,
{
type: 'text',
value: '\n \n \n \n \n \n \n \n '
},
// ...
