Videos embedded in a plugins readme.txt does not load while searching for a plugin in an actual WP install (not wp.org)

If you embed a video within your plugins readme.txt file it only shows the video on the wp.org website, videos do not load when you're searching for a plugin via an actual WordPress install. In addition, if you install a plugin and click on "View Details" to learn more about the plugin, the video also does not load here either. Inspect element shows an empty span tag:

<span class="embed-youtube"></span>

This should either embed the video or at the least display a link to the video.

Here's an example plugin for reference: ​https://wordpress.org/plugins/simple-icons/

Hi there welcome to wordpress trac! thanks for the report.
Replying to thememason:

I don't really get this one, can you explain more?

<span class="embed-youtube"></span>

This should either embed the video or at the least display a link to the video.

I'm able to reproduce this one.

Hi @azouamauriac

If you search for plugin name, while adding the new plugin, and click on more details and see the README, you would see that only span tag for embed video. So all in all, before install if you click on the more details button and preview all the details you would be able to reproduce the same.

Let me know if this works? Else, I would add a screencast for this.

Thank You,

This PR addresses an issue where embedded videos in a plugin’s readme.txt file do not load when searching for plugins within a WordPress install or when viewing the plugin details modal.

• Videos embedded in a plugin’s readme.txt file display correctly on WordPress.org but do not appear within the WP-Admin plugin search or the "View Details" modal.
• Inspecting the element showed an empty <span class="embed-youtube"></span>, indicating that the embedded video was stripped during sanitization.

#### Root Cause

• In plugin-install.php, the function install_plugin_information() sanitizes the plugin data using wp_kses().
• The $plugins_allowedtags array, which defines the permitted HTML tags, did not include support for <iframe>, causing the embedded video to be removed.

#### Proposed Solution

• Added support for the <iframe> tag within $plugins_allowedtags, allowing embedded videos from sources like YouTube and Vimeo to be retained.
• Applied CSS rules to ensure iframes are properly sized within the plugin details view for better UI consistency.
