Mdx: Self-closing hyphenated shortcoded tag is different when not void

[valse]

Subject of the issue

Hi, I'm dealing with a strange behavior: if I set a shortcode like this:

const shortcodes = {
 "cc-image": Image,
}

<MDXProvider components={shortcodes}>
   <MDXRenderer>{data.post.body}</MDXRenderer>
</MDXProvider>

and I use it self-closed

# Title

Paragraph

<cc-image />

the rendered html is like:

<h1>Title</h1>
<p>Paragraph</p>
<div class='image'></div>

if I use the same component but not self-closed, the final html include an extra wrapper paragraph for the component itself:

# Title

Paragraph

<cc-image></cc-image>

the rendered html is like:

<h1>Title</h1>
<p>Paragraph</p>
<p>
   <div class='image'></div>
</p>

Expected behaviour

Even if not self-closed the component must not be wrapped in an extra paragraph.

I don't know why but it happens only if the shortcoded tag includes an hyphen :-/

Thanks for reporting! This looks like a bug in the remark tokenization.

Also, strangely enough, if there's a newline between the open and close tag it _is_ parsed they way we'd expect:

# Title

Paragraph

<cc-image>
</cc-image>

Weird indeed! This will be fixed in 2.0.0 as we’re rewriting the parser to solve amongst other things, this problem!

I’ve confirmed this is indeed fixed in the v2 prerelease, so going to go ahead and close this.

If you want to give it a shot now: @mdx-js/mdx@next.
