I've sent simple html-formatted message with image inside the body to my Mailman 3 test list.

On "Held messages" page there is 'View' button and it was disappointing that this feature just show a source code of message (35 thousand lines because of image attached).

When I approve the message it went to the archive but with no proper html rendering also. The html was simple formatting and it become attachment.html file which even cannot be opened in place, just downloaded.

Are there any plans to show html messages nicely in 'View' feature and archives?

Thanks, Danil
