Subject of the issue

Two lines with self-closing JSX tags seem to have issues:

error  Parsing error: unknown jsx node: "<Hero />\n<Featured />"

Steps to reproduce

import Hero from '../components/hero';
import Featured from '../components/favorites';

<Hero />
<Featured />

Expected behaviour

The parser should be able to handle two separate self-closing JSX tags on subsequent lines.

Actual behaviour

The parser throws an error.

Please provide a minimal runnable reproduction.

@JounQin Here you go: https://github.com/cpboyd/bug-mdx

yarn
yarn lint

And you should see the same error.

[JounQin]

This error is thrown from https://github.com/mdx-js/eslint-mdx/blob/master/packages/eslint-mdx/src/traverse.ts#L57
and adjacent self-closing jsx nodes are not parsed separately, it can be handlered by wrapping with <$></$>, I'll try to fix it ASAP.

[JounQin]

@mdx-js/maintainers Should that be parsed as separated nodes via remark-mdx?

[JounQin]

@mdx-js/releasers Would you like to publish a patch version by yarn publish?
And is NPM_AUTH_TOKEN available in the GitHub Actions?

[JounQin]

@cpboyd Would you like to check whether v1.6.6 works?

[cpboyd]

@JounQin it works, thanks!
