 The WordPress.org plugin directory
 [https://meta.trac.wordpress.org/browser/sites/trunk/wordpress.org/public_html
 /wp-content/plugins/plugin-directory/class-plugin-directory.php#L573
 supports several embeds], specifically `[youtube`, `[vimeo`, and
 `[videopress`.

 Most of these embeds appear to return `iframe` elements, which are removed
 by Core, see [https://core.trac.wordpress.org/browser/trunk/src/wp-
 admin/includes/plugin-install.php#L533 $plugins_allowedtags].

 For example, the Updraft Plus plugin has an embed on the WordPress.org
 site, but not within the WordPress Add new plugin screen.
 If you have Jetpack installed, it appears that it converts the `iframe`
 into a shortcode and displays that instead.

 This was originally reported as #meta2846, see that ticket for an example
 of the HTML that's stripped by this behaviour.
