Reputation dropdown says: +2 notification. Going into details, it also shows +5, +2 and +2 reputation all for the same "edit" being completed.
This certainly seems like a UX bug to me, because it's sending several unclear, mixed messages.
For starters, I thought I got +2 only (white text, green square). Then, I thought I got +5, or +7, or +9, depending on how the little green +N numbers are supposed to add up (green text).
What's really happening here? Can we improve it? Did I find an actual bug? :D
