What operating system are you using?

Linux

Describe the Bug

When you clone the Astro Starter Kit: Blog with Multiple Authors example and have block posts where raw HTML is part of the content like:

<ul>
    <li>Pieter Levels <a href="https://levels.io/async/">https://levels.io/async/</a></li>
</ul>

Astro generates content like

<ul>
<li>Pieter Levels
<a href="https://levels.io/async/"></a><a href="https://levels.io/async/">https://levels.io/async/</a>
</li>
</ul>

It seems that if the content of the <a>-tag is also a URL, the markdown parser automatically generates an additional (empty) <a> tag.

See screenshot:

Expected result

Output generation like

<ul>
<li>Pieter Levels
<a href="https://levels.io/async/">https://levels.io/async/</a>
</li>
</ul>

This definitely looks like a regression with our Markdown handling! We're still trying to track down a few remaining issues like this. It's a high priority to fix!

@natemoo-re In v1.0.0-beta.31, it is working as expected. In v1.0.0-beta.36 it is broken (like described here).

I assume cfae976 might be a good start (part of astro@1.0.0-beta.33).
