4:30 PM - This passes QA on XenForo.
Once the rest of 4.0.16 passes, it will be released.
Marking this as Implemented in 4.0.16. It appears in the changelog under Bug Fixes, since this feature was a regression. While there are related open regressions, this report is closed because the description in the OP is satisfied. As mentioned earlier, related regressions will be addressed in a future release.
