Tests to ensure that some kinds of events are stopeed at shadow boundary.

On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".


Other events than "click" should be stopped at shadow boundary.  A "click" is added for the purpose of comparing results.

An event fired on a distributed child should not be stopped at the shadow boundary of its host (host2), but should be stopped at the nearest shadow boundary (host1).
