Unfortunately the patch that was supposed to fixed this caused a
regression and was therefore reverted. Rob (Cc'ed) said there was a
patch to fix it properly and was supposed to go into 3.6 but it seems
that never happened. Rob, what's the status on this?

The revert is here: bc51b0c22cebf5c311a6f1895fcca9f78efd0478
