If a guest user submits a comment and completes the Website field, that URL is clickable on their username even if the URL is removed/edited in the WordPress comment admin section.

For example if a guest user enters the website http://www.xyz.com when completing the Comment form, and a moderator removes/edits that website address either before approving the comment or after approving the comment, their name still has the original URL clickable in their name.

The uncached page still shows

<div class="wpd-comment-author ">
<a href='http://www.xyz.com' rel='noreferrer ugc nofollow' target='_blank'>Name</a>

even though the URL field is blank or changed to something different in the WordPress comment section.
