Codepen does not render React and plain DOM element

JavaScript
1

What am i doing wrong?

in the Codepen html window i have:

<div id="app"></app>

<hr style="background-color:red;height:1px" />
<p>
This should render regardless of React, it is outside the mount point.
</p>

You’re accidentally closing your div tag with an app tag.
