I only get "Failed" email notifications, never "Fixed" afterwards

In my user settings, under “Notification Settings” -> “Default Email Notifications”, I have the option “Send me a personalized email every time a build on a branch I’ve pushed to fails; also once they’re fixed” selected. However, I only get emails saying when a build has failed, never when it’s fixed again! (I’ve checked and it’s not because they’re in my spam filter.)

I assume this must be a bug, unless there’s some separate setting I haven’t found that controls these notifications. It would be great to get this problem sorted.
