Confirm that re-dispatching a cached click doesn't satisfy notifyEvent()
When a DOM event is manually dispatched, its isTrusted bit is set to
false. This makes the event ineligible to use with
window.fence.notifyEvent(), even if the event was trusted initially.
This CL includes a WPT that verifies this behavior.
