$.fn.delegate does not reflect event.preventdefault() from earlier $.fn.bind

[rjgotten]

When an event has its default behaviour prevented in a handler added with $.fn.bind(), a handler higher up the hierarchy added with $.fn.delegate() reports that the event does not have its default behaviour prevented.

Provided is a ​jsFiddle illustrating the issue:

1. The bound handler executes.
   • The event's default behaviour is prevented.
   • A reference to the event object is retained.
2. The delegated handler executes.
   • The event's status is checked with isDefaultPrevented(). It returns false.
   • The reference to the event object is compared with the retained reference from the bound handler. The event objects are not the same event.

The event delivered by .bind() is on the actual element, but the one delivered by .delegate() is on the delegated parent element. They are not the same Event object as the test case shows. I think it should be possible to initialize the propagated event to reflect reality though, I'll try some tests.

When a native browser event is bubbling up the DOM, make sure that the correct isDefaultPrevented value is reflected by jQuery's Event object. Fixes #7793.
