Previews for non-dreamwidth commenters

[denise]

[This suggestion was made an OpenID user, and the posting process failed because OpenID accounts can't post to communities; the suggestion was good enough that I just sent it straight to Bugzilla, but I wanted to record it here for posterity and so that my numbers can match up.]

Summary:

If HTML links will be disabled, can comment previews show this?

Description:

Comments by open-ID or anonymous users do not permit HTML links or images (or maybe that's just an option on the journals I've commented on). Can the preview option be changed to detect open-ID or anonymous comments and show them as they will be rendered with the links disabled?
