Affected package

Steps to reproduce

import rehypeParse from "rehype-parse";
import rehypeRemark from "rehype-remark";
import remarkStringify from "remark-stringify";
import { unified } from "unified";

const processor = unified()
  .use(rehypeParse)
  .use(rehypeRemark)
  .use(remarkStringify, {
    fences: true,
  });

const main = async () => {
  const vfile = await processor.process(`<p>A<span><br /><span>B</p>`);
  console.log("RESULT", vfile.value);
};

main().catch(console.error);

I believe #66 introduced this.

Basically a <br> might not be directly under <p> but under <span> and under such conditions removing it breaks the output.

I found this while processing clipboard data that came from MS Word.

Thanks!

Note: your input HTML does not close its spans. That is likely not what you mean.
I also recommend not using superfluous things such as the / on the br — it seems like it does things but it does not

You're right, sorry I was a bit too quick with the sample.
