fix drag handler test for IE. for whatever reason, ie and ff handle the tests in different order. because IE runs through the functions numerically, the constructor test is run first, and so the changes to the handler's initialize are maintained throughout the rest of the tests. thus, we need to make sure to set it back before exiting.
