E.g. T87884 was created and that's the subject of the mail I got: [Maniphest] [Reopened] T87884: Convert BetaFeatures to use extension registration
Clearly the task was created, not reopened. Tasks got created by @Legoktm via a script.
Also the mail body misses the typical line "... created this task."
