Bugs are sent to to the tech support team.  FWIW, though, it's already been
fixed in the internal development version of Mathematica, along with a few otherrelated issues such as the handling of Super/Sub Plus and Minus.

For now, you'll have to remember to explicitly use the FullForm version of,
e.g.,  SuperDagger[x].
