- Fixed bug that affected generally the same classes of event
as that of :ticket:`3199`, when the ``named=True`` parameter
would be used.  Some events would fail to register, and others
would not invoke the event arguments correctly, generally in the
case of when an event was "wrapped" for adaption in some other way.
The "named" mechanics have been rearranged to not interfere with
the argument signature expected by internal wrapper functions.
fixes #3197
