Comment 2 for bug 504409

Well, now it _adds_ tags consistently (with one exception I'll get to), but it will not remove tags consistently--if any of the subtasks have been edited, the tag will remain (but this isn't true on a tag that hasn't been edited). Now, if a parent task contains edited subtasks, and you manually type in a tag, you'll end up applying a new tag for each letter that is entered (with results that look like @t @th @thi @this) in each of the edited subtasks (but it works fine in non-edited subtasks).

Also, this is my own personal preference, but I like the ability to apply tags to a parent task without affecting the subtasks. That's just me, though--that it works consistently is much more important than that. :)
