I believe it is coaslescing 'duplicate' events.
Your explanation of the changes you did make here reinforces why I think it
should probably be changed to equals() now. Before your changes, it wasnt
possible for the == check here to do the wrong thing. Following these changes
in future it will be possible (even if not that likely) for this to do the
wrong thing and it wont necessarily be the easiest thing to find then, whereas
it is just now.
