Forum Replies converted to Idea Comment URLs appear to not Redirect appropriately

(Still on 12.0.2.17146)

Had an issue reported to me with the internal URL redirect engine that seems to be deep under the hood. A Forum Thread was moved to an Ideation as an Idea with the option to convert replies to comments enabled. The URL in the emails for the original reply is in the format:

{siteurl}/{Group Name}/f/{ForumName}/##### (Thread ID)/{Thread title}/##### (Reply ID)

This would work normally if the reply stayed a reply to a forum thread. After the thread was converted to the idea, the redirect engine creates an internal redirect in this format:

{siteurl}/{Group Name}/i/{IdeationName}/{Thread title}/##### (Reply ID)

instead of the permalink format that would work:

{siteurl}/{Group Name}/i/{IdeationName}/{Thread title}?CommentId={Comment GUID}

This results in the "Page Not Found" page being displayed instead of going to the content.

Is this a known issue in this version that has been resolved in 12.1.x? (I took a peek at the release notes but didn't see anything that matched)

If not, any ideas on a workaround or can we capture it in a ticket to resolve in the future?
