Comment edit and preview

Is there a site that lets a user edit WordPress comment text in WYSIWYG and then delivers the HTML for pasting into a WordPress site comment box?

Failing which, lets the user edit in HTML, and previews how it will appear in a Word press comment?

This is to help users work around the following still-outstanding WordPress messups: https://www.ads-software.com/support/topic/wp-messes-up-onm-literal-text-misinterpretable-as-html?replies=17

Thanks.
