event delegation does not work

this adds some failing tests for event delegation.  i think i may have some
other tests to add too but just wanted to use these to start the conversation
about how delegation should work.

some of the other things i want to test are:
* stopPropagation prevents delegation as expected
* when global handlers are called in relation to other handlers (before, after)

let me know if delegation is supposed to work some other way so that i can get
it working in my project and try to add some other tests for that way.
