It was easy enough so I just built the Tampermonkey script. Tampermonkey lets you run small scripts to modify web pages when they load. In this case, I check if the comments link doesn’t point to the forum and attempt to fix it. Both the bookmarklet and new approach are here. Tampermonkey is only for desktop browsers and Firefox for Android, but I hope it makes this problem just go away for those who can use it. Let me know if you have any issues.
